I run an imageboard on vichan as well.
After a few weeks I started getting automated CP attacks. At first I was upset and just deleted it all and contemplated turning off the server for a few days.
But then I got mad and figured out exactly how their attacking and figured out how to block it.
For what its worth I know what tool they attack with even but that doesn't help much. I also reported all the IPs to the appropriate abuse emails but thats a black hole.
I messaged who ever runs the lefty pol twitter but got no reply.
I want to share my defence methods with leftypol in a way that attackers can't see how I did it (i dont wanna publish it on git or something). Message me back on twitter if your interested in automated CP blocking, it supprisingly wasn't that hard.

Remember please try to reach out to other admins of other imageboards so we can share data.
Current admin of an altchan here, I recommend getting the user's browser's fingerprint and blocking that fingerprint. They are most likely running some Selenium Python bot that opens Firefox in headless mode, so being able to detect whether or not it matches these conditions
>using firefox
>is headless
Might help with curbing the CSAM spam. However, innocent users who just use firefox just because might be affected by this, which is also why I recommend trying to get more info such as
>what OS the bots are using
>what ports the bots are using
I recommend you use the canvas JS API to find information like this and check every time whether or not a user posts it matches the canvas of a banned user. If it matches, it autobans the user for ban evasion. It's been working like a charm to get hostile users of splinters of my altchan off.
Isn't there some kind of AI program that will automatically detect and remove cp?
