A post at Flippa that's a vast improvement over some previous ones, IMO.
Summary:Below Iíve outline some strategies around selling your social media profiles as part of your website sale on Flippa. Iíve included the 3 most (currently) popular social media services, so if there are others you want to transfer, make sure you check with the appropriate terms of service.
Facebook: You can't change the admin (though you can create a new user)
Twitter: You can sell a username as part of a business but not on its own
Youtube: Assumption is that you can sell
Are you aware of the rules for social media accounts elsewhere?
Have you sold a social media account with your site? Or acquired one when you bought another site?
What about forum accounts?
I suppose I shouldn't be saying it here, but I've three Sitepoint accounts I acquired with websites I bought (though, I hasten to add, I don't use them).
