HI @Lind111,

Thanks for using the new template. Wanted to check in with timelines for you on this application.

With the Holiday break coming up the teams will be ooo until January which means you may not see a Watchdog or Governance comment until that time.

Warmly,
-Kevin

SmallArt Ltd.
The client did not update all the Storage Providers (SPs) used for deals.
For most SPs on the list, there was duplication, averaging about 10% per SP. Although this percentage is not high, it should still be monitored.
Out of 7 SPs:

• 4 SPs have a retrieval success rate of 0%,
• 1 SP has a retrieval rate of 7%,
• The remaining 2 SPs have a retrieval rate of 41%.

WorldBankGroup
In the previous review, it was noted that the client is working with multiple allocators simultaneously. Was this issue discussed with the client after the review?
Of 14 SPs, only 2 have a retrieval success rate at a satisfactory level.
SP performance details: SPs F03166666, F02639492, F02368946, and F02362412 have duplication rates below 20%. While this rate is relatively low, it should still be monitored.
The allocator continues to run CID reports and requests explanations from the client when discrepancies are found.

AMEstadium
The data preparation information provided by the client is inaccurate. The allocator did not ask follow-up questions, even though the client mentioned that the dataset would be prepared in tar or zip files. These formats are not suitable for storing data on Filecoin.
Although the client claimed the data had not been stored before, at least two applications have been identified with identical data samples and descriptions:

• DAYOU
• MAX-CoinSummer-Labs

The dataset is marked as "open," but its description suggests it is private and not publicly accessible. There is no index or verification to justify the reported 650 TiB of data.

Additional issues:

• The allocator requires at least four SPs, but the client is currently using only three.
• SPs f03238633 and f01531188 are using a VPN, which violates the application rules.

[Lind111]

@Lind111 SmallArt Ltd. The client did not update all the Storage Providers (SPs) used for deals.

Are you referring to the updates to be made to the application form?
Clients have disclosed in advance in the comments
Lind111/EF#34 (comment)
Lind111/EF#34 (comment)

• 4 SPs have a retrieval success rate of 0%,
• 1 SP has a retrieval rate of 7%,
• The remaining 2 SPs have a retrieval rate of 41%.

I have been following up on the retrieval rate, and at this point the client has not provided a reasonable explanation and will not trigger a subsequent DC

I'm wondering about the open source retrieval tool that the client mentioned here, is this recognized?

WorldBankGroup In the previous review, it was noted that the client is working with multiple allocators simultaneously. Was this issue discussed with the client after the review?

This one I did notice, and I realized that the client was storing different data, so I didn't ask too much about it

Of 14 SPs, only 2 have a retrieval success rate at a satisfactory level.
Client explains database crash, it's fixed

AMEstadium The data preparation information provided by the client is inaccurate. The allocator did not ask follow-up questions, even though the client mentioned that the dataset would be prepared in tar or zip files. These formats are not suitable for storing data on Filecoin.

My understanding is that the client compresses it into a tar or zip file and then uses the appropriate tool to make a car file for storage.

Although the client claimed the data had not been stored before, at least two applications have been identified with identical data samples and descriptions:

• DAYOU
• MAX-CoinSummer-Labs

The dataset is marked as "open," but its description suggests it is private and not publicly accessible. There is no index or verification to justify the reported 650 TiB of data.

This client has just started applying and is currently in the second round,I'll follow up on those questions.

Additional issues:

• The allocator requires at least four SPs, but the client is currently using only three.

The latest report now has 4 SPs spread across 3 different regions

• SPs f03238633 and f01531188 are using a VPN, which violates the application rules.

The current client explains and provides supporting documentation in the comments

@filecoin-watchdog Finally thank you for your review, if there are any other issues please feel free to point them out, thanks again!

[Lind111]

• SPs f03238633 and f01531188 are using a VPN, which violates the application rules.

The current client explains and provides supporting documentation in the comments

@filecoin-watchdog I would like to know the way you check VPN，As well as confirming that the client's response proves that he is not using a VPN

@Lind111
One additional observation regarding the AMEstadium client:

I retrieved a random piece from their dataset. Fortunately, the data is retrievable; however, the content of piece baga6ea4seaqibmmmvxms6k5uw7qfborr7jb5zvevu7zs2heicrhl3b4q26vwsdq from SP f03238633 consists of screen recordings of someone playing Subway Surfers. Below are two example files from this piece:

Questions to consider:

1. Is this really the data that was declared to be stored?
2. Does this data hold significant value for humanity as claimed?

[filecoin-watchdog]

I'm wondering about the open source retrieval tool that the clienthttps://github.com/Lind111/EF/issues/34#issuecomment-2563410039, is this recognized?

I don't recognize this tool. You can always ask the client what they are using. It also looks like the clients might not understand how that works. I recommend checking the official spark documentation https://docs.filspark.com/troubleshooting-miner-score#block-3c41a58cb03f4a8593924d0af9e8800b

This one I did notice, and I realized that the client was storing different data, so I didn't ask too much about it

In the previous review, Galen has said:

Overall good diligence and compliant behavior. It would be good to see how this allocator is investigating clients that are working with multiple allocator pathways. It is reasonable for a client or data preparer to be working with multiple teams, but there should be investigation, diligence, transparency, and justification for that behavior. (...)

This is why I asked if you did any follow up after the third review.

---

My understanding is that the client compresses it into a tar or zip file and then uses the appropriate tool to make a car file for storage.

Was this confirmed with the client or is it your assumption?

I would like to know the way you check VPN，As well as confirming that the client's response proves that he is not using a VPN

For SP f03238633: https://www.ipqualityscore.com/vpn-ip-address-check/lookup/103.25.202.111
For SP f01531188: https://www.ipqualityscore.com/vpn-ip-address-check/lookup/47.242.91.210

[Lind111]

@bashyang Thanks for the clarification.

[Lind111]

@filecoin-watchdog I'll follow up on these omissions, I've benefited greatly, and thank you again for your detailed review that

[filecoin-watchdog]

@Lind111 Would you like to respond to my last comments, or do you feel everything has been explained?

[Lind111]

Client accounts are banned and comments as well as request forms have disappeared
The following was previously clarified

[Lind111]

@filecoin-watchdog Sorry, I was waiting for your reply.

[filecoin-watchdog]

@Lind111 I didn't see the above comment before it disappeared, hence the confusion.
Well, I guess there is nothing more to say about AMEstadium.
If any DC needs to be revoked from this client, please notify the gov team.

[Lind111]

This is his last report.
and documents proving his geographic location.

[Lind111]

If any DC needs to be revoked from this client, please notify the gov team.

Got it. Thank you.

Checked to see that the client has already used up the second round of DC

Hi @Lind111,

Thanks for submitting this application for refresh.
Wanted to send you a friendly update - as this works its way through the system you should see a comment from Galen on behalf of the Governance this week. If you have any questions or need support until then, please let us know.

Warmly,
-Kevin
