Pop collaboration WhoHurtYou released its new single, Wish We Never Met, along with a Twitter tool that matches that sentiment.

Wish We Never Met-erator enables Twitter users to log in and delete all of their interactions with another Twitter account, either one at a time or all at once.

People log in with Twitter to activate the tool, which uses the social network’s application-programming interface, and they can only delete tweets they posted with mentions of the person whose memory they are trying to scrub.

Wish We Never Met-erator does not violate Twitter’s terms of service, as the social network noted that there are no rules against apps that delete tweets in bulk, cautioning that once those tweets are deleted, they cannot be restored.

Twitter also said apps built using its API must go through its developer application process and are reviewed on a case-by-case basis.

WhoHurtYou teams up All Time Low guitarist Jack Barakat and Kevin Fisher, a songwriter who goes by Sweet Talker and has worked with artists including OneRepublic, 5 Seconds of Summer and Anitta.

Barakat introduced Wish We Never Met-erator by tweeting about it to his 1.8 million-plus followers.
