Guardians of the Galaxy star Chris Pratt took to Instagram to warn his followers of an imposter using his name and pictures on Facebook.

Pratt, 38, warned his followers of the fake account and referred to the announcement as a “pervy dude alert” according to the New York Post.

“It’s confirmed: 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,” Pratt warned, urging fans to look for the verified blue check mark to determine the legitimacy of the profile.

“Please know, I find this behavior reprehensible,” the Parks and Recreation alum continued. “If I find out who it is I’ll have their account shut down and seriously would like to punch them right in the GD mouth. You hear that, impostor!? Stop.”

The actor pleaded with his fans to spread the word about the fake account, hoping to prevent kids from falling victim to the treachery and expressed fear for their safety.

“It terrifies me to think someone could be hurt, their feelings or much worse, by this impostor/potential predator.”

Since Pratt’s whistle-blowing, the imposter account has been deleted from Facebook.

“Claiming to be another person on Facebook violates our Community Standards, and we have a dedicated team that’s tasked with helping to detect and block these kinds of scams,” a Facebook spokesperson told sources.

The social media company is working towards a way to eliminate fake accounts entirely.

“We’ve developed several techniques to help detect and block this type of abuse. At the time someone receives a friend request, our systems are designed to check whether the recipient already has a friend with the same name, along with a variety of other factors that help us determine if an interaction is legitimate,” the statement continued

“It’s an area we’re continually working to improve so that we can provide a safe and secure experience on Facebook.”
