If I tried to answer every single request to chat,even with a simple "No Thanks " Two things would happen, first I would never have enough time in the day to answer everyone, bearing in mind that to say "No thank you" to say 20 people, would probably take up about 15 minutes of my time, all the time new requests come in. Secondly I have been met with abuse by the moron who does not like being told No.
Far better not to reply, and instead concentrate on the one adult I have managed to find, and give him the time of his life online.
