Can I get my number checked and removed?
"Dear owner/moderator of this website, can you please remove my private phone from your website set up to warn prostitutes about dangerous punters. I'm a good punter honest, I'm just worried about being outed."
"Yeah, sure, Mr. Anonymous Concerned Punter, just give me your private number, and wait five minutes whilst I run that through our database, I won't be contacting the police or warning prossies about you, honest."
In all seriousness though, some stones are better left unturned. Don't be a nonce and you should have nothing to worry about. If really worried, then change you private number, make sure everybody you know gets your new number, and always stick to using a burning SIM in future, and stop worrying so much about what stupid bloody prossies websites are up to.
