A group calling itself ‘Overweight Haters Ltd’ has reportedly been handing out a series of abusive cards to passengers on the London Underground.

According to various reports on social media, select passengers are being given the fat-shaming notes – which apparently come from an organisation that “hates and resents fat people.”

“It's really not glandular, it's your gluttony...” the cards read. “We object to the enormous amount of food resources you consume while half the world starves. We disapprove of your wasting NHS money to treat your selfish greed. And we do not understand why you fail to grasp that by eating less you will be better off, slimmer, happy and find a partner who is not a perverted chubby-lover, or even find a partner at all.”

“We also object that the beatiful (sic) pig is used as an insult. You are not a pig. You are a fat, ugly human.”

One Twitter user, Kara Florish, claims that she received one of the cards on Saturday, and defiantly shared the news on her social media accounts. “I am smaller than the national average and not exactly obese,” she posted on Facebook. “But this is hateful and cowardly and could potentially upset people struggling with confidence and eating disorders.”

Another user, journalist Sean Thomas Knox, said that he saw a similar thing happen while on the tube at Oxford Circus yesterday. According to his tweets, a “smart, trendily dressed”, “hipster” man quickly got on the tube to give one woman a card, before swiftly jumping off again. “She read it and cried,” he wrote. “Her stunned, desolate reaction was very real. Then tears.”

Other victims have yet to come forward – which is pretty understandable given how damaging and destructive this kind of abuse can be. However, both TfL and the British Transport Police have assured that they are investigating the claims; and are urging anyone who has been handed one of these cards to contact them. “All of our customers have the right to travel with confidence,” said TfL in a statement. “This sad and unpleasant form of antisocial behaviour will not be tolerated.”
