Chris Pratt has kept a relatively low-key social media profile since splitting with ex-wife Anna Faris in August, sharing just a few updates mostly in celebration of his upcoming Avengers: Infinity War appearance. But he posted an important Instagram update on Thursday night to warn fans about a fake social media account that has reportedly been contacting fans in his name.

“PERVY DUDE ALERT!!!” Pratt started the post, making sure to clarify that what he was about to share was not a joke. “Somebody is trying to pretend to be me on Facebook (and maybe other social media platforms), apparently hitting on a lot of different female fans, trying to get their numbers and who knows what else. I’m not joking.”

The Guardians of the Galaxy star went on to call the actions reprehensible and promised to try to have the account shut down. “[I] seriously would like to punch them right in the GD mouth. You hear that imposter!?” he wrote. “Stop. My message to any fans who are contacted by someone claiming to be Chris Pratt: Look for the BLUE ‘VERIFIED’ CHECKMARK next to the name. If there is no checkmark by my name that person is an imposter. I’m sorry.”

Pratt disclosed that the person posing as him on social media and contacting fans is not an isolated incident, and urged his followers to look out for each other.

“Tell your siblings. Educate our young ones. It’s probably mostly kids who would fall for this. Makes me sick,” he wrote. “It terrifies me to think someone could be hurt, their feelings or much worse, by this imposter/potential predator.” He concluded his post by again warning the person responsible and demanding they stop. “Praying for you,” he said.

It’s possible that Pratt’s warning worked: The fake account seems to have been removed from Facebook. Stay safe out there.
