The micro-blogging platform Sina Weibo has begun purging posts and comments that carry the hashtag #les, which is short for lesbian. The quiet ban was first discovered by users of Weibo’s “super topic” (超话) feature, which allows individuals to create online communities organized around hashtags. Weibo users are also no longer able to use the rainbow flag — widely recognized as a symbol of LGBT rights and social movements — in their bios.
