Less than a week after Google released its “Transparency Report,” Twitter has now done the same. On Monday, the San Francisco-based company released its second such report, covering the second half of 2012.

The company said that in the final six months of last year, 815 “user information requests” came in from governments and law enforcement agencies around the world. Of those, 81 percent were from Twitter’s home country and 60 percent came from American law enforcement agencies. Twitter complied in whole or in part with 69 percent of all requests worldwide.

Like Google, Twitter is now breaking out what type of legal tool was used to force the company’s hand. The company wrote on its website that of American requests, 60 percent were subpoenas, which have a fairly low legal standard under the Stored Communications Act.

“They do not generally require a judge’s sign-off and usually seek basic subscriber information, such as the e-mail address associated with an account and IP logs,” the company wrote.

Eleven percent of US-based requests were court orders signed by a judge, and 19 percent were judge-signed probable cause-driven warrants. The remainder, the company said, “do not fall in any of the above categories. Examples include exigent emergency disclosure requests and other requests received for user information without valid legal process.”

Twitter reiterated its company policy to “notify users of requests for their account information unless we are prohibited from doing so by law or in an emergency situation,” as articulated in its Guidelines for Law Enforcement.

Twenty percent of requests from American sources were issued under seal, meaning “a court has legally prohibited us from notifying affected users (or anyone else) about the request.” In contrast, 24 percent of the time the company was able to notify its users.

The remaining 56 percent of such requests fell into neither category—either because the request was withdrawn, was defective (wrong jurisdiction, no valid Twitter username), was an “exigent emergency disclosure request,” or had another related reason.
