Before you get into the microtransaction system, I'd like to explain that perhaps there was a community that liked what she was doing. Maybe she was taking donations. Perhaps she was a codemonkey on the side who was doing a lot of custom quests. Fact of the matter is, the microtransaction system could be anything. It could be used to vilify her because she wasn't going to go to a court that was against her from the start.
Trust me, she didn't do anything to benefit the community.
I used to play there (4 years ago and for a week, before I played on the official WoW realms proper), and what honestly baffles me most were people who were willing to fork over that kind of money for very poor service and uptime.
The reason she used microtransactions was to provide players with really out-there items in game. I don't know what items they were, having never entertained the idea myself, but I would imagine they must have been of great value if people were throwing money at her with the full knowledge that the money wasn't used for the upkeep of the server. Plus the constant barrage of advertisements begging you to donate "otherwise the server would go offline" seemed to be a good enough scare tactic for teenagers.
I roughly remember the time when she began using the donated money for her own personal expenses. She directed about $3000 of the donations to some kid with cancer without the approval of the community, despite her own TOS saying that the donations would only be directed to the upkeep of the servers. Problem with contesting this fact was that anyone who said it wasn't right to direct money to non-server causes was painted as an asshole (and since it was to a kid with cancer, it was a fine line to tread).
Then she started using the money for treadmills and all those things, I believe. There was a brief hoo-ha in the community demanding she produce proof that the treadmills were bought with her own money. She gave them the big go-around ("oh, the transaction is with my friend, I can't access it, she changed the password, she's out of town etc.") and then just plain banned everyone who brought it up. I didn't really follow the drama thereafter.
There were a lot of key people and customers who kept jumping ship, so I'm actually quite surprised she managed to keep it afloat for so long before getting caught. The biggest attraction that she provided was that it was a popular free server (and I imagine a fairly good one before those key people decided to leave), and way back then, whenever you Googled "wow private server" it'll be the first search result.
Blizzard isn't that foolish to believe they'll ever see a penny of that 88 million. Peyton wasn't "the weakest" by any means - she buoyed her extravagance on well-meant donations by the community through an illegal means of transaction. If she is the person amongst all the others who run private WoW servers to be punished and scare the others into
not making a profit off their game, it's well deserved.
