Every ad I see on the site lately is for penis enlargement or meeting up with people for sex. Are these ads really appropriate for a site where children come to play chess? 

I have paid for membership, so don't see any ads. I must agree with you though, the content outlined above is wholly innappropriate on a family chess site.... I wonder if Erik is aware of these ads? I can't believe he would allow it if he knew.

Have you contacted the staff here with your concerns?

Is there a contact link somewhere?

I have never seen these. That would upset me too.

I think you should approach admin directly about this. I am positive they don't want these types of ads. Remember, it is not chess.com's decision which ads pop up for users. They would want you to report these.
