Probably a bad analogy but enough of this...
So Ivan your out on a date and you start coming onto her in a way she doesn't like. She tells you to stop but you persist. She slaps you and runs off then accuses you of attempting to do horrible things to her. You ask her later why she did that. She says, I told you to stop and you didn't. You say...well you didn't warn me I was going too far. Yeah...that doesn't hold up in any court in this land. No means no.
When a Mod says enough, that is your warning. Some will attempt to exhaust all options before they get to flagging an account but the moral of the story is...don't violate the guidelines in front of them. I've been with Urz when he had to flag an account because a guy was behaving trollish. He was told to stop, he didn't. Not even for a CA.
The CA clearly said enough and to cut it out.
