In saying that, a lot of pictures on twitter of models are not postmarked and look great. These often end up on other sites around the 'net.
Like zookie said, as a rule of thumb either:
Only post watermarked photos (18 and Busty, DDF Busty and Scoreland have all featured Anna Song)
or
Post where you got it from, Twitter or instagram etc
Anything from a site called 'the fappening' is probably not a great idea, they steal a lot of stuff from Only Fans.
Like I said, I'm not here to stop anyone's enjoyment of the BEA, I just have to be careful about what is posted. I used to flag up verboten posts to the Mods in the past, but as I am the sole mod now, the buck rests with me. It is a thankless job.
