Personally, I like VMK just the way it is. Most of the bans are fair (there are some unfair ones, but they seem to be resolved most of the time) and most of the people who get them do deserve them if they are giving out personal info in VMK. VMK to me seems to be a promotional device for Walt Disney World,
Disneyland, and all the other Disney parks. I don't think they would make people pay to use a game that they could very well be using for marketing purposes.
Even if they did decide to make VMK a subscription service, I think they should keep the bans because people shouldn't give out personal information to others anyway. There is enough of that going around on Myspace, and it could be potentially harmful
Just my two cents...
