Most new accounts are not making any posts at all, meaning three months later they become archived.
most likely those are accounts that got proxy-banned and abandoned by the users
and probably some are accounts that actually got nuked by admins
There's a third category: New accounts prepared to start a spam run when needed. Considering the large number of new accounts, it's either bots registering, or a clickfarm. I wouldn't be surprised if spammers pay people to register new accounts.
If they're proxy-banned, they're most likely abandoned. But if they slip through, it's stockpiled for later use.
I find plagiarism easier to deal with that pure one line shitposting
It depends: the plagiarism bots quickly evolve: they now shuffle words, replace them by synonyms, and/or do a
homograph attack.
Lately, I (and others) have gotten many homograph-bots banned. I think this actually hit them, because for the past few days, barely any new homographs were posted. The homographs were actually easier to get banned than "normal" spam, I don't know what they're using now.
Just like
bump bots now use
self-moderated threads to circumvent the 24h delete restriction.
