If this thread tweet from Mobius isn't enough proof for you...
Then here is some more collusion I've come across at the tables in recent months.
(Hero)CO opens. SB 3bets. BB calls. ^
BTN opens. (Hero)SB 3bets. BB cold 4bets. BTN goes all-in. ^
(Hero)UTG opens. MP calls. CO calls. SB calls. BB squeezes. ^
(Hero)CO opens. BTN calls. BB squeezes. CO calls. BTN goes all-in. ^
All these involved accounts exhibiting the typical bot characteristics during their time at the table. None of them were playing like recs. And this is only a small sample of what I've seen from them in recent months.
