If you show up posting that someone is a pedophile but don't include any corroborating evidence to back up your statement (e.g. a link to a news report or police statement) then expect your post and account to be deleted.
I am not the police. I am not able to verify information that isn't in the public domain and there are enough malicious idiots about who will use libel to smear and harass people that we'd be crazy to take any statement at face value.
