A report by Twitter revealed that about 7% of claims (less than 1,000 out of almost 13,000 claims) made during the first half of 2015 that other accounts have violated its trademark policy have resulted in suspension of the offending accounts. Twitter contends that the reasons that so many claims are denied include that: (1) notices were filed by unauthorized representatives of the trademark owners; (2) notices failed to provide sufficient information to locate accounts or infringing content; (3) notices related to non-trademark issues; and (4) notices were challenged by the account holder after suspension.
