“People often say to me it’s great that players can now open up about their struggles,” he wrote. “Can they really? I certainly wouldn’t encourage it.”
Caulker, who was capped once by England, alleged bet365 had rejected his profile due to the operator being “nervous” about some of his previous campaign work.
However, bet365 has said its position was misrepresented to Caulker by a media partner.
“Mr Caulker applied to appear as a guest on a video series solely sponsored by bet365, which is only published on an online video platform (not TV) by one of our sports publishing partners,” the operator said in a statement.
“During the guest approval process, we became aware of Mr Caulker’s own negative experiences with gambling which he has spoken about openly.
The video series and the sports publishing partner in question are still unknown.
Caulker’s comments come with the UK currently engaged in Safer Gambling Week 2023.
He has returned to LinkedIn this morning (15 November) to reveal further elements of his life as a “compulsive gambler”.
Caulker, who has been without a club since leaving Wigan Athletic in May, said he has a voice in his head that talks to him every minute of every day, encouraging him to gamble.
“Whilst all this is going on internally, I am faced with hundreds of adverts a day trying to lure me back in,” he wrote.
“Every football match I watch, every football match I play, every YouTube highlight, most newspapers, most radio stations, most TFL services, and if that wasn’t enough, I still get text and emails,” he added.
