How did those accounts get created in the 1st place? Arent there captchas? Or are there ways around that? Strong captcha system should he implemented in lemmy by default
Captchas are a low bar to modern standards. All the advancements in AI are a problem for captchas. Machine vision tools have become abundant and simple. Unfortunately, I'm not sure what more you can do except require human review of access.
I'm not sure about all of them, but at least some of these instances did not have captcha or email verification enabled when they were first set up. They were easy targets for scripted account creation
Capthas are ineffective since a ver very long time
