Its a hive of misinformation, disinformation and toxicity. Its succinct I guess, but nothing is eloquent or descriptive because of the character limit. And its full of repetitive "filler" information.
Who wants that in a foundational LLM dataset?
Maybe its OK for finding labeled images... But that still seems kidna iffy.
I mean as far as uses for LLMs go that seems to me a pretty realistic one. Mass quick propaganda with little effort. Go for immediate impact, doesn't matter if people look deeper, you're just looking to get a swell of emotional reactions.
