I’m a trifle surprised(given Twitter’s…limited…‘monetization’ success and ongoing efforts in that direction) that they don’t offer a “professionalize” service to people and companies running twit-feeds for things they deem important enough to pay for:
Bundle a supply of proper 2-factor hardware fobs(with management portal to delegate and allow/deny specific permissions to the various sub-accounts that exist invisibly behind the single public account), along with scrubbing or replacement of this sort of metadata to make tracking the origin of specific tweets by client impossible(you obviously can’t fix style; but Twitter could report whatever ‘posted with’ values they wanted).
For customers accustomed to TV ad buys, Twitter could charge fairly audacious prices for that technically pretty minimal service and still seem like a real bargain; and it would prevent various hacked-account and intern-off-the-rails problems.(or at least could be sold as doing so to the people who will actually go off the rails and wish that rogue media interns were the problem…)
