Google has deactivated ads from the site, mentioning that it contains Pornographic/Nude pictures.
However they do not provide a relevant URL...

Anyway, to avoid future problems, if you find nude pics (in comments or even maybe vehicle picture), it would be nice to report them here so I can eventually remove them, as I prefer to have Google's money than having a few random nude pics provided by Sixcyl and others.

Also, to reactivate ads I have to provide a few URLs to Google where such pics were removed.
