Here's something I noticed that can help identify AI-assisted shitposters:
OP's post has flawless English. Perfect punctuation, grammar and capitalization.
Without AI assistance, their posts look more like this:
Dear mk4
Thank you for your Detailed Reply i will read and watch your all suggestion on the links
actually I have money for Invest but i am confused about this crypto market
I already check history too much Dump and Pump i cant afford loss
Ironically my post satisfies the portion of OP's question about addressing spam.
The real question is should AI-assisted shitposters be tagged for shitposting if their posts don't necessarily fall under the spam category and hence won't be deleted by mods.
