Oh I don't think that is something you could be banned for. Though I do always appreciate the compliments. I work really hard to stay good looking (I don't even care if that sounds vain, if I feel pretty I feel better typically)
As far as sharing pics goes I was a model when I was younger so now I hardly bat an eyelash at the idea of a stranger seeing a pic of me. Also I figure if the picture is already on the internet somewhere then realistically stressing about someone I don't know seeing it is just silly.
