The WSJ reported yesterday on Twitter-style cybersquatting - unauthorized Twitter accounts created using a variation on a company's name. The story provides a number of examples, including one where a marketing consultant admits to opening an account in the name of an amusement park company in the hopes of trading the account for a free pass.

According to the article, Twitter will institute a verification service this summer, but companies won't be protected. (The service will "confirm profiles of public officials, public agencies and other well-known individuals.") Yet another reason companies should actively monitor their brands online.
