好一个天道酬勤

Meaning

Refers to being hurt despite doing nothing. Popularized by Weibo blogger @纤维粒 (apparently friends with 怨男0), who often posts this phrase. He's the "Wang Wentao it's 1:30am when are you turning off the lights to sleep" guy. The funny part is his fans comment "纤维粒 didn't hurt anyone" on posts "slandering" him, pretending to defend him while actually enjoying the drama. Later evolved into "XX didn't hurt anyone" format.
