Twitter and Instagram I can understand, there are a lot of people on those services that make a lot of money promoting brands and products. Having an interesting name on there can increase your marketability. Like "@tom" or "@lisa", you look cooler (rather than "@realmattdamon1977") and seem like you've been on here for quite awhile so therefore people should listen to you. I guess it might be a bit hard to show that you bought an account versus stole an account if the original owner tries to reverse the email address change. Maybe someone could build an account escrow site where ownership is transferred to a third party until the sale is complete.
