Twitter vulture 

People who search through old tweets to uncover racist, sexist or mostly out of context, non politically correct jokes or statements. People who think they're symbols of virtue but are essentially garbage collectors for likes and retweets.

"Peter is a Twitter Vulture, he's searching for old racist tweets on the people he follows"
