Bots are trying to join my instance now through the application requirement (lemmyverse.org)

I have the application process enabled for people to join my instance, and I've gotten about 20 bots trying to join today when I had nobody trying to join for 5 days. I can tell because they are generic messages and I put a question in asking what 2+3 is and none of them have answered it at all, they just have a generic message.

Be careful out there, for all you small instance admins.

... How many comments would each of 5M bot accounts need to make to overflow an i32 db key ... I also think it looks as if someone is testing disruptive stuff. It may be kids playing, or it may be the chatbot army in preparation.

I'm not a Postgres expert but a quick look at the pgsql limits looks like it's 4 billion by default, which uh, makes sense if it's a 32 bit limit.

Soooo 5 million users would need to make.... 800 posts? ish? I mean, certainly doable if nobody caught it was happening until it was well into it.

Aha that's a postgres default? I was looking into the code to see some of the DB structure. And i thought, well i made over 100 comments in 2 weeks so it wouldn't take too long until that 32-bit space is used up (in normal operation with some more users).
