If the Washtowel had financial interest in MySpace, they wouldn't have threatened to remove "privileges" for peole with MySpace accounts a couple of years ago. What is happening is "They said something about Facebook, but they didn't say anything about MySpace--so I will go onto MySpace". And they will do the same thing there.
And, when the hounder-hounders find out, they will start cracking down on all such sites. They recently had a problem with witlesses starting their own discussion group on Facebook, and they are cracking down specifically on that site because of that.
