I suffered from the hit-and-runs a lot. Impolite and demanding, most of the time. It got so bad at one point that I had to add a disclaimer to my signature. People were asking me stuff about watches I've never even posted about, or asking me which dealer that has blacklisted me would be best for them.
Still, if I get a PM from someone whose name I've seen in a post or with a VIP tag, they'll get a proper reply. If they're a no-post-noddy with the stock signature, they now get Toady's Noobie guide instead of a reply as it usually answers everything they were asking and going to ask.
Seriously, why would anyone ever ask me if Davidsen's PAM012345 was better than Trusty's? I've never professed to be a Panerai expert, I've never bought from Davidsen and Trusty dislikes me. Post-count and rep can be a burden.
