I'm a member of a site called Myfreecams and some-one has put an abusive comment onto my profile and want to know how to remove it..
Please help

You ask the operators of the site. It will be up to them.

The way things are handled here are probably different then they are there.

Talk to whoms in charge!

Who creats your profile, you, can you not edit your own profile ?

Is it a review of you postings ?

But you will have to talk to the owners of the site, or the people who moderate and control the activities there.
Some sites have better control than others
