The founding editor of Business Insider UK, Jim Edwards, had a bank delete two of his tweets today. In an e-mail, Bank of America told Edwards that his tweets violated the bank’s copyright and that if he kept it up, they’d see to it that his Twitter account was deleted.

“Investment banks apparently have the power to censor journalists on Twitter, simply by asking,” Edwards wrote in a short post on Business Insider describing the situation. “That is depressing.”

Edwards had quoted a research document produced by analysts. He says the tweets were “probably trivial,” but can’t really be more specific—in part because the frequent Twitter user can’t even remember exactly what they were about.
