Between August 24 and September 14 last year Robert Bedford used an app to communicate with a number of girls he believed to be under 16.
The 49-year-old expressed a desire to perform sexual acts on children, court documents state.
But Bedford, who went by the username Robert B-Shyguy, was actually sending messages to decoy accounts run by paedophile hunter organisations.
On September 15 he found himself face to face with paedophile hunters who live streamed the confrontation until police arrived to arrest him.
Bedford was then charged with four counts of attempted to engage in sexual communication with a child.
On Friday (March 21) he appeared at Bexley Magistrates’ Court where he pleaded guilty to all four charges.
His case was sent to Woolwich Crown Court where he will be sentenced at a later date.
Bedford, of Wrottesley Road, was released on bail with conditions not to have any unsupervised contact with children either in-person or online.
