The last two are the same idiot, possibly all three are the same. They only get 5 daily posts per account and seem to use all of them. I don't even read their garbage, just delete as soon as I see the username.
Ironically, the only poster to actually get banned by Admin recently was Nmbr1stkpckr.
To your question about the uptick, they didn't post that much for a long time but have certainly ratcheted-up their nonsense in recent weeks. Either they are being compensated by some entity shorting/accumulating or they're just sad trolls in need of attention.
