Matthew,
I can look at Ggreg's posting history and identify when he was acting like an ass. I cannot look at yours. Why is that ?
Because, being the owner of CathInfo, I have a higher profile and a bigger target painted on my back than any other member.
When one wants to do harm against an Internet foe, having a convenient method of browsing through ALL his posts is an invaluable resource -- which I happily deny my would-be attackers, slanderers, persecutors, etc. My posts are all public, but you have to sort through 1/2 a million (actually, it's well over 565,000) posts to find them all :)
