This should never be acceptable at any time, hobby or not, the sad thing is that a lot of the times, the women (and men) that endure such abuse will not turn it in.
They feel somehow it is their fault... and then with in the hobby world there are some ladies that will not report such thing account they are afraid that some of their
peers will tell them if they would have screened better then it would not have happened... that is total bullshit in my opinion.
You ladies need to always, no matter how much you might dislike one another, stick together when it comes to safety.
You need to get the word out, even if it is through private channels and not on the open board, about any and all such violent persons.
History has shown time and again that what starts as a little slap here and a punch there.. can turn into much more serious things later.
How would you feel if you didn't tell others about that violent person and the next girl he sees, he puts her into the hospital or god forbids, kills her.
So please ladies, share this type of information with each other.. if it helps just one girl not get hurt.. don't you think it is worth it.
