Well first off SweetiePie91, your name is very similar to one of the most popular WGT players who has been on here for a long time. That might have something to do with your huge number of invites.
I have no problem with whatever picture anyone wants to post, free to do as you please. I would say that if you posted a full head to toe picture in a bikini you might not get as much attention as just a picture that is focused on your top with not even a face. I would suggest that you change it to a generic picture for a few days and see if that helps and then go back to whatever picture you want to put on the site.
