Could the other 2p2ers at my table, please stop berating the fish.

I don't think it could ever be unethical not to allow players to be rude to other players. But of course this is up to the cardroom in question.

And of course it could be +EV in the short run. But I don't ever think it can be +EV in the long run when recreational players are involved. When it is in a setting where it is just serious players playing each other, I'm not as much against it, even though I am actually still against it.
