Hi there, Been running my own little Lemmy instance basically to see how it runs with federation and stuff like that. I have had open (email validation) for the odd person or 2 that might want to use it.

Early this morning (my time 4:43am) I had about 15 new users all at the exact same time registering as users with same structure names (random words) followed by 4 numbers. Being all within 1 minute of each other they are obvious bots.

Going through the UI I have not been able to find a way to remove them. I have since changed my registration policy to make the person fill in an application, captcha, email validation etc. to help stop polluting the ecosystem with bots.

Any help would be appreciated. I am running it all under docker

    I experienced this on my own little instance as well, although they managed to create 69000+ users before I noticed that something weird might be going on and I got a message from a helpful soul indicating the same thing.

    I was pointed to a writeup by lemmy.ninja @ https://lemmy.ninja/post/30492 on how they experienced this and proceeded to clean everything up, and adapted this to my own instance. Only thing to mention of note was that I disabled triggers while doing the cleanup. The DELETE statements on person table was excruciatingly slow to the point where I estimated that time to completion approached 48 hours.
