I tell some guy I'm colluding. Is this OK?

[Ungoliant]

If you want to be an idiot and claim that you're cheating, it's stupid, but I see nothing wrong with it. Just don't come here whining about how much Stars' support is overreacting to your "joke" when your acccount is frozen. However, accusing an innocent player at the table of collusion is not cool at all. I would be extremely pissed if I was the BB here. Being accused of collusion is no joke. Even if he suffers no punishment from Stars, there are other people at the table who he may have to play against regularly in the future, who now think he's a colluder.
