I have been saying for years that Twitter should just take a page from Internet domain name providers and just have a yearly fee for the re-registering of your Twitter handle. These Twitter handles are in some cases more important to brands then even their domain names. I would gladly pay for the 7 different Twitter handles that I currently Tweet out information on. Since domain names are about 10-15 dollars I think $5.00 would be a fair yearly registration fee. This revenue source could very well take Twitter to another level of profitability.This would also cut down on all the folks who get fake Twitter accounts in order to do more harm then good. It would also cut down on Twitter trolling and give those of us who do take Twitter seriously the ability to be one step bellow the verified accounts. Speaking of them I would keep them where they are and maybe even have two types of verification. Blue for corporate brands and Gold for entertainers and sports figures. The rest of us would have a paid yearly registration symbol that would certify to all that we are a legitimate Twitter user.
