Hellfire, I'M using a fake name on here, so I would hope that all models do the same as a matter of course. (Why I am using a fake name? I have a few things in a few media fires, nothing enough to be known yet, but when I do finally get that BAFTA nomination in a few years, I'd rather not have it be exposed that this is part of my recreational enjoyment!)
That said, I've worked with a few actresses in short films, and believe me, this is not an exclusive problem to WAM. Any information about anybody on the net, even if it's only a name, will in this day and age lead to something like this. Some delusional sees a video and thinks that that girl would just love to be his new best friend, and bingo, one facebook search later, you have harassment.
I understand the temptations, but hey, just because I follow Eliza Dushku on twitter does not mean she wants to know all about me and I have the right to expect her to reply in kind. Sadly, some people's brains have a logic and civility bypass and some of them share our fetish. Basic precautions (fake names and the like) are all you can take, but taken they should be.
I also hope if I ever chanced upon a model from any of my fave sites, I'd just smile politely, say love your work, and move on. (Though if I chanced running into Fi Stevens the headline would read "MAN DIES INSTANTLY OF HAPPINESS")
Oh, and producers, if any transgressors are found to live in the Devon/Cornwall area, please let me know and I'll happily go punch them in the throat for you.
