We have a problem with repeat scammers ripping our members off in our classifieds forums. Since the data protection people stopped us from publishing the details of known scammers, we are somewhat helpless to stop them. One considerable help would be a conversation monitor which creates an alert for selected mods/admin when specified key word(s)/phrases are sent in a conversation. E.g. A match on at least one key word or phrase (maybe a Person's name, phone number, bank account number, street name or post code) sent in a conversation creates an alert with a particular message pointing to a thread or previous user profile. We could then step in to ban the scammer and warn the intended new target.
