Twitter has won kudos for being relatively resistant to spam. That may change. Rocketboom founder Andrew Baron, not pleased with the level of interaction his account has generated, has put it up for sale on eBay.

It would be silly to just delete this account I have here, especially if there is someone out there that had like interests and had something to say or wanted to get involved in some relevant conversations.

By "something to say," we assume Baron means "something to sell" — after all, why else would someone up the current bid of $1,525? In order to reach Baron's 1,635 followers with breakfast updates and cat photos?

No, it's to leverage Twitter's potential as a generator of links which increase websites' ranking in Google's search results. The good news for heavy Twitter users is that this sets the price of followers at around a dollar each. Maybe following every single account that adds you, spammer or otherwise, isn't such a bad idea after all. The only reason top Twitter user Jason Calacanis isn't selling his account? He's already using it for spam that promotes his business. (Photo by Dummycast.com's JA Donnelly)
