There have been a number of comment spam attacks in various posts in a couple of /c’s that I follow by a user/individual who uses account names like Thulean*
For example: [email protected] in [email protected]
and [email protected] in [email protected]
edit: Also [email protected] in [email protected]
The posts have been removed or deleted by the respective /c’s mods, and the offending accounts banned, but you can see the traces of them in those /c’s modlogs.
The comments consist of an all-caps string of words with profanities, and Simpsons memes.
An attack on a post may consist of several repeated or similar looking comments.
This looks like a bored teenager prank, but it may also be an organization testing Lemmy’s systemic and collective defenses and ability to respond against spam and bot posts.
That takes more effort though, especially if accounts require some kind of “not a robot” thing, like email verification, submitting an “essay,” etc. I’m not a fan of that and think a different moderation system would be preferred (prefer to not go into details here), but it’s easy and should be quite helpful.
It’s not a “fix,” more of a mitigation.
Typical mistake by the comment above yours: anti theft of anti break-in measures dont make it impossible to break in, they just make it harder and more time consuming. You dont need to outrun the bear, you just need to outrun the person next to you.
So this absolutely is a great idea.
