Sometimes some people can say lots of rude words to anyone and just show total disrespect. Some people can be really angry cause of bad beats, or if someone can call with nothing or with bad hand and get lucky and win something.
I understand, that sometimes it,s hard to control yourself, especially if you were playing a couple of hours in a tournament and lost hand cause of someone play it bad, but was lucky.
Anyway this is not OK at all to say any rude words at the poker tables. If someone say something rude, just make a screenshot and send it poker rooms support team. Maybe they will not ban this people at all, but they can lock the poker chat for that players and maybe next time they will not say this rude words, and no matter why they are saying that.
Who knows, maybe some people use this rude words as a game plan just to take off someones patience.
