As an online Poker player, the most important factor for me is to make sure that all my co-players within the table is a legit person and not a bot. It is my most concern of all things in poker and until I don't know how to verify it unless they are chatting in the chatbox. 
Yes as a poker player I also think like that, it is strange to see there is one username in many rooms which makes me think that they are bots because of that i prefer to play in the tournament because the opportunity to play for one person only once.
