Spam handling

[tassoman]

Any idea how to prevent spamming?
There are activitypub spammers who implemented a way to spam instances each-others.
When I try to deactivate or delete any of this accounts (b8b, 33bet, s666bet, dubaipalace), Delivery Queue gets flooded with 250 events. Then I found there are 10-13 delayed activities for other tens of instances (for about 124 delayed outgoing activity)

I guess they have developed something who spams other instances on deletion event. So instances are spamming each other.

I found #7091 #7088 #7089 #7090 issues related to spam, can be related

Jobs can also get stuck if the instances no longer exist and thus cannot complete. For example, mk.disqordia.space is no longer in service. The Misskey forks Calckey and Foundkey clear job queues from dead instances unlike Misskey.

I realized jobs went to that instances while Instances were un reachable. I can't say if I flooded them or simply they were offline for own problems 🤔
BTW the activity was contextual of profile deletion. Profiles weren't following and weren't followed by anyone. I can't say the reason why of such that activity

maybe this was an effect of forkbomb vunerability just discovered some days ago? 🤔

Doubt it.

Sorry for digging an old post.
How do I can delete nowadays spammy users, messages and attachments?
Spammy account can only be suspended (2024.02.0)

Deleting the user should erase everything.

[tassoman]

Yes, indeed. I confirm user deletion can delete everything from that user.
The feature is only available to administrators, no user deletion for moderators.
It's a first step for manually spam deletion.
More on this, today an antispam filter is under deployment.

Anti mention spam handling can be configured using roles
