Originally, I considered moderating posts, but I hate to have to delay any legitimate Jamie news from being posted as soon as possible. So, instead, I'm opting to moderate membership. This seems the least intrusive way to combat the spam problem. No one who has posted spam here is a long standing member of the comm or an actual new fan who just discovered the comm. Since all the spammers have brand new accounts and have gone on community joining sprees, they'll be easy to spot.
Hopefully, this will put an end to the spam problem while not dissuading any individuals with a genuine interest in Jamie's career from joining.
