You're a few years too late to the party. The winning regulars at HSPLO and SSPLO who know what to look for haven't spotted new(er) bot accounts playing the regular ring tables recently, but no you're right, gotta watch out for all the bots and collusion at the play money tables.
. Also ~90% of all hands played at 2/4+ (which is HSPLO according to 2p2) are played at zoom with almost the entire player pool consisting of longtime regulars and players who are clearly recreationals, there aren't any new mysterious winning regulars these days, so your post is in the wrong forum.
