The Ban was approved, so I can't speak to that - whats done is done - even if it is stupid, and over-extreme.
However, she was not "consulting" with the tattoo artist, she was showing off to the tattoo artist. Levi, (the tattoo artist) being such the "gentleman" that he is at 1-3am, while mostly blitzed was not about to tell her to "not" take off her shirt, especially considering she offered to.
This was not in a private area - it was in an main common area of the hotel, somewhere she should not have been revealing anything anyway.
The Bra she was wearing had shoulder support, when Thomas unsnapped it - nothing was shown to anyone, she wasn't already showing.
She at first didn't know who had done it, and wasn't even that angry about it, aside from how annoyed girls usually get when it happens. This did not change once she found out who had done it.... Until "girl friends" goaded her into having a larger problem than she did.
I am not going to say, that despite her openly putting herself into a situation, that every other woman at the event for the last 11 years has known better that she isn't a victim. What I will say, is that in order to be made a victim, there first has to be a crime - and loss of Support to the ta-tas, is not a crime... its annoying & Sexual harassment at worse (which wouldn't hold too strongly considering her behavior and location)
It was High School, drama, childish behavior at a OWbN event, while drinking, somewhere around the 1-3am time frame (Surprise, surprise). Some things go without saying, and are to be expected - whether we like them or not.
Feel free to be a Jackass, Jackass isn't against the OWbN Bylaws (you may just loose friends) - Don't put yourself into a situation where stupid shit can happen - and hopefully, with luck... it wont.
