They post memes, they shitpost, they sow chaos. Hell the person who wrote that might have been one of them trying to freak everyone out based on the insanely-inflammatory language used. They've always been one thing, and that's unpredictable.

But "hurt" does not come from unpleasant or offensive images. Also I have to laugh at "they may also come for reddit". They'd be ripped off the site within moments, reddit has a negative-tolerance(it's like zero tolerance but they have so many extra layers it seems like it's in the negatives at this point) toward anything like that. This reads like the old "if you don't share this, you'll never fall in love again" chainmails of the 90s.
