Again smiths, I cannot be held responsible for what another individual tweets or posts on here, no-one can.
If this person really thought that was your real name, that is a despicable action that can't be condoned in any way, I'm definitely not in favour of anyone's real name being outed by others whatever the provocation, that is low-life tactics. You mention gloves coming off, I hope you aren't considering retaliating in kind by trying to out someone else, as that would put you in the lowlife category too.
I looked at the Twitter timeline for that markpartylover and he's been retweeting other party providers, mentions visiting other parties, mentions his banning on here, visiting various escorts, going to a mate's stag do, etc, etc. His last retweet of TPC was back in June, so it doesn't look like a sockpuppet account. He seems like a party guy/punter to me. I can't imagine someone going to the bother of inventing all that just to get a few retweets of TPC on there, but if you know differently...
I fully understand how you would be upset/annoyed by what this idiot did, but as it stands, you weren't actually outed, you can just pick another alias and be totally anonymous again.
