Going to the gym can be a discouraging experience for many who feel intimidated by some of the super-fit exercise enthusiasts who work out there. It probably wouldn’t help if you knew that one of those people was talking junk about you behind your back.

An Australian man posted photos of patrons at the gym and mocked them with captions such as this one: “Here we see the amazing chicken man. His 2% body fat is admired by bodybuilders and bulimic teenage girls alike.” Reddit and 4chan’s “fit” board figured out about this, and they weren’t having any of it. They obtained the guy’s personal information, called his mother and told her all about her son’s commentary, and called the gym manager to explain the same thing.

As a result, the guy’s mom cut her son off financially, and the gym owner banned him from the entire chain of gyms.
