What would I do? First, email the admin/moderators and ask them to remove the post. Past that, untd.com is an ISP it would appear (ww.untd.com) and most likely uses a proxy server, so it could have been any of their users. Figuring out who on the internet doesn't like you is futile at best. If I spent time researching every idiot on BFHP that tries to start crap, I'd be up to my eyeballs in IP addresses.
As to Harpo's question... why does everyone pick on Staci? Because he/she has put a target on his/her back. When you share personal information, especially the kind that is not mainstream, you invite such crap. Staci is also well known for wearing her heart on her sleeve. Again, in a world of internet bullies, you've just handed every idiot with nothing better to do, their own personal can of whip arse AND a can opener.
Staci's situation is certainly unique, and is not mainstream nor accepted by a definite large minority if not the majority. If you couple that with the fact that there is no shortage of openly opinionated people on the internet who do not have to answer for their actions, it's almost gasoline with matches. Sooner or later, someone's gonna get burned.
Staci, as for which person is typographically assaulting you, you and all of us have far better things to worry about. Sure, it'd bug most any of us to have such comments said about us, but in the long run, you have to file it away in the "go procreate with yourself" file and move on.
Now I'm known to have a tendancy to not sugar-coat things and to not go back and read what I've written to see if it can possibly be taken wrong, and I'm not doing it with this one either. Staci knows good and well that if I have a problem with her, I know how to email her and tell her what I think. This was not intended to be a bash of anyone, in any way, shape, or form.
