We have noticed that a certain kind of profiles has no profile image. These profiles are created by robots and they are only trying to post a link to mainly two types of sites. Medicine for huge erections and hard core adult sites.
They are using these kind of marketing because Google gives them a really hard time getting indexed.
The consequence is that all FREE profiles older that three months will be deleted! If you have a paid membership, you are home free. We are NOT going to mess with that!
