If this has already been discussed before, please point me to the relevant threads and I'll move on.

What are the "ethics" involved in online games with the chat box, as it relates to saying what you folded while the hand is still going on (i.e. flop K-rag-rag... chat:"damn, folded a K")

Is this a line that you're just not supposed to cross (kinda like hitting a gal ), or is it just "part of the game"? Saw it happen twice tonight, and wondering if it is a "tool" that could be used in the right situation, or would it get accusations of collusion, whether you know anyone at the table or not.

Any thoughts?
