I looked up their main stats on Poker Edge and they are very similar like you said.
VPIP PFRaise winning BB/100
Mr_Hand 10.00% 4.73% 18.70
FearIt 10.07 % 4.60% 24.46
pbandj 9.97% 4.64% 25.12

I think when ever I play them in the future I am going to see if they answer on chat and warn the other players they may be bots.
