I had this happen most recently about a week ago.
I've had my profile shut down around 4 or 5 times because a troll has stolen my profile photos and even bought my private gallery pics!
Months ago they made a facebook profile with my pics and told adultwork that I had stolen my photos from this FB profile! I disputed this and sent them evidence which showed that the FB account was only made recently, and therefore they had stolen MY pics from AW.
It was a lot of hassle and AW are generally quite useless
This most recent case was a troll making money using my PG pics using a popular 'chat flirt and show off' website (not sure if I can name it).
It was quite frustrating but I got in touch with the admin of the aforementioned site and explained to them that this person had stolen my pics. They were quite helpful and shut the fake profile down.
I've also had copycat AW accounts made, which were derogatory and quite quickly shut down after contacting AW and having clients contact them also.
Best thing is to contact the admin of whatever site your photos are on and explain your situation. Send screenshots where applicable and being polite but also a little 'desperate' always helps.
I've experienced all sorts of trolls, Twitter death threats, copycats, here there and everywhere, so have become quite the expert now!
AW have apologised for all the inconvenience and there are now 'notes' on my account which let the AW team know about all the troubles I've had- I think they are on my side now! (Blimey!)
