We had a guy on the one snowmobile forum doing that and someone fell for his or hers bs. Cost the guy a couple hundred bucks in new parts for his snowmobile. Few of us said to ban him as he was trolling or just flat out stupid. Once someone finally took his advice and that happened. That guy came back and just tore him apart. Mods/Admins finally banned him, he tried to come back under another account. I walked the one mod who is a friend through an IP Ban and it worked. Haven't seen that idiot since then thankfully.
