Hartlepool coach Sam Collins' Twitter feed has become an overnight sensation after it was apparently taken over.
The former player and assistant manager's account put out three messages, making allegations about his personal life.
The posts have been retweeted more than 2,000 times.
A club spokesman declined to comment on the situation.
Collins joined Pools as a defender from Hull City in 2008 and twice served as caretaker manager before being appointed as number two to Ronnie Moore.
He has been working with the club's under-21 side since the arrival of Craig Hignett as manager.
