MacAnthony took aim at the club on Twitter on Monday as the January transfer window drew to a close.
Citing the club's missed payments over a transfer, MacAnthony explained why League One outfit Peterborough were unable to bring any new players in before the deadline closed.
MacAnthony posted on Twitter: "Ok Posh fans, there won't be any incoming signings today but that has nothing to do with players having to leave etc.
"The real reason is due to a certain championship club failing to make an agreed large payment (not thousands btw) last week on plyr [sic] they bought from us.
"This same club did this to us in August & now again. Truthfully it's a disgrace and their chairman is the same.
"It has put us last minute in a terrible predicament which I shall now fix & once loan window opens, we shall bring in a couple of players to help the squad.
"It's also a shambles the Football League allow this nonsense to carry on & not for the first time.
"I'm also sure we are not [the] only club who it's happened to but the knock on effort is outrageous & doesn't help a club like @theposhdotcom [Peterborough], that's for sure.
"I don't like having to share this on Twitter but our fans deserve to know why it's been a quiet day.
"I have other chairman fair warning that I wouldn't be messed around & that all within the game will know this, should he not pay up.
"Sad thing is that he can afford to!!"
