I'm not sure this is an issue at most sites, but I play at ACR and twice now a player has been chatting (obnoxiously) in a three-way pot. My understanding was that talking in a pot with more than 2 players is not cool as it may influence the game unfairly. Is that still standard or do online players ignore the old-school ways?
I'm sure you have heard of the term liquid-courage. Well people get internet-courage.
For the most part people will say almost anything that they wouldn't dare do in front of a live person.
It is ONLY 1 player per hand & the ONLY players that are allowed to talk about the current hand are the people involved & that is ONLY if it's heads-up. If it is a multi-way pot then everyone should shut up.
At casino I play at there is ABSOLUTELY no speculation even if it's heads-up.
Generally the rule is if not heads-up then everyone should shut up & then if heads-up ONLY those 2 participants are allowed to say anything.
If I were you I would take down the players name & the hand number & the table & the time of the hand & report it to support. I would also go to ACR's twitter address & post it online so the whole world can see what their response will be.
Unfortunately if U only do it through support via e-mail they have a standard reply & the issue isn't resolved. That is why it's best to go through twitter to get a "real" answer instead of something scripted.
