We are not authorized to remove threads at members' requests ... because the threads belong to all of the members ... not just the one who started it nor the model it happens to be about. We only remove threads if they are in violation of our rules or it's a duplicate of another ongoing thread.
If you are a model and it's impacting your career, you may have your agency contact the administration to explain why certain public photos need to be removed. On occasion they will remove specific photos if the reason is valid ... but they almost never remove an entire thread.
Advise your agency to do this by using the "Contact Us" link at the bottom of any forum page. Have them provide their agency email so that the identity of the person can be verified ... and have them provide a link to the actual thread in question. They will advise your agency of their decision.
