Twitter came under fresh criticism over the weekend after the service blocked some search results using a variety of terms related to the LGBTQ community including both "bisexual" and "queer." Even as photo and video searches for these terms were blocked, critics said plenty of white supremacist and other hateful content remains on the site.

Why it matters: It's the latest criticism against Twitter for its uneven policing of content on its site. Twitter declined to comment beyond a vague tweet that said it had "identified an error with search results for certain terms."

Jim Halloran, chief digital officer for GLAAD and former head of global content management at Twitter criticized his former employer for again blocking LGBT-themed content.

This isn't the first time Twitter has been confronted for blocking LGBTQ-themed content, nor is Twitter the only tech giant to struggle with the issues. Google's YouTube came under fire after it was flagging a wide swath of LGBTQ videos as "restricted content."
