I'm gonna be contrarian here and say this is a Good Thing. It's very easy to tag to tag this sort of writing, and that makes it an absolutely great signal about hte people who post it. The more vacuous or frequent it is, they less weight you can accord them and the easier it probably is to get past their filters and make use of them for your own ends.
Is that morally bad? Guess that depends on exactly how you make use of them and what those ends are. If you an encourage an idiot to praise your competitor's product in order to get a reverse halo effect, that's kinda bad. If you give them some empty flattery in order to bridge a contact with someone you actually want to connect with, that's probably OK. The point is that uncritical LLM repetition tells you something about the person and lets you see past metrics like the apparent amount of wealth they have, the intimidatingly deep resume, or the degree size or centrality of their network. Two things, in fact: they post any old thing that brings in the clicks, and they're cheap. Previously many of these people probably paid someone to ghost-write their commercial affirmations.
Conclusory zinger goes here - punch up the dramatic contrast PS I'm reducing your fee to 10c/word, hope that's OK. Inflation
