my hobby is wanky
Over on the animanga cel forum there's been a series of wanky threads over the past couple weeks

Thread 1 Guy is selling some DBZ cels. High quality and higly sought after by those who collect DBZ cels, meaning the prices are high. Some-one just has to come along and bitch.

This one is in two parts
Part one Collector posts about a situation between her and a dealer asking for advice. Because the dealer in question is one of the largest and most reputable she doesn't name names. People are pretty angry and giving her advice until the seller pops into the thread, and basically bashes the collector. And people post in support of the seller.
Part 2Collector posts again and people wank on both sides of the issue while others yell at them to shut up

And the third one Every so often a collector gets outbid in an auction. It's annoying and and frustrating, a condition multiplied by x100 when the winner immediately turns around and sells the prize(or tries to) for a profit. Legal, yes, but it leads to ranting Which in turns leads to wanking.
