I think that those people who use the chat to have an advantage against other players, simply do not know how to have a good game strategy, or do not know what playing poker is on equal terms, either skillfully or psychologically.
online poker is very different in terms of communication at the tables! when you play offline it’s impossible to sit for 6 hours at the table and be silent, but when you play online from 6 to 20 tables, you don’t have time to chat, and therefore many people never answer you! it's not rude - they just can't afford it!
I've personally met all kinds of people online, some are really nice and even called me a 'pro' lol while others throw insults whenever they lose a hand especially when someone from Brazil or Poland gets the better of them.
I guess polish and brazilian players have a really bad reputation.
Would you say the same about Phil Hellmuth? He definitely seems to have the same kind of mindset.
