CHARLTON ATHLETIC have threatened supporters by telling them they will cancel their season tickets unless they sign a behavioural contract.
The English League One outfit have been in disarray over the past couple of seasons, and fans have regularly protested and criticised the board.
And now Charlton have told fans they must sign a contract that stops them from posting critical comments on social media about the club.
The letter was received by a fan who then posted it on Twitter, where they are told that they must signed an “Agreed Behavioural Contract” or they won’t receive their season ticket from the club.
