I quickly put together a list of all of the accused (in addition to two more I've spotted on my own) at mainly the 25nl limits and some 50nl, and here are the results. I dashed out some stats that had less than a handful of sample sizes and did my best to put in parenthesis the ones with very limited sizes as well.
Obviously sample size will be an issue as some of the stats reported would take some time to converge (4b, F24b, River samples [cb, xr]). The ones we can look at with some significance would be VPIP, PFR, 3b, F23b, CO/BTN/SB steal, WTSD/W$SD/WWSF on those with more significant samples, and the ones most telling to me are Flop/Turn CB-XR, and postflop agg%.
This is my opinion of the suspected based on these stats at first glance.
Inconclusive due to sample size: 6, 9, 11
Does not share same overall trends, probably not bots (at least from same origin/programmer): 12, 16
Worth looking more into: 10, 15
Probable bots: 1, 2, 3, 4, 5, 7, 8, 13, 14 -- These are the ones with 5k+ hand samples and share the nearly identical VPIP, PFR, 3b and the same trends for CB stats, F2CBs, agg%)
To be honest I'm not sure how concrete the evidence is, but the trends are definitely alarming. I had 4 of these guys marked as "does not understand ranges!" But they're still either BE or slightly winning players.
If any of you more savvy-stats guys spot any patterns or mistakes feel free to discuss in a civil manner. Also if any WPN staff wants the excel sheet with names revealed I'll be happy to provide.
