I have very little respect for someone who shows up in forums - online communities - and spends just about every post they make trying to convince someone to buy into something they are trying to sell. I for one refuse to buy items from people who do this, even if I was interested in the item itself. It may not be overt spam, but it's freakin' annoying.

Especially when you get all sanctimonious when someone calls you on it. Spam is spam, Sam I am, and you have earned my "ignore" hammer.
