He was indeed @dradrianharrop but changed his handle to @adrianharrop.
Since around March 2019 a series of troll accounts appeared on both Twitter and IG that targetted Harrop and Hayden. IG had #TroonOfTheBailey that really got under Tony's skin. He tried to draw the homo-diver Tom Daley into the fight. on account of a post about their surrogacy (see Hayden's thread for details). Tony claimed the post against Dailey was so horrific it was illegal. Bullshit of course because the original appears on the Conservative Home website (see Hayden thread).
On Twitter there was @RealLadyLawyer, again targeting Troon Tony. There were more: @sxsligo (which was a take over of some poor unfortunate, innocent Irish guy called Mick O'Hara), @ForMutha, @woman_face and a take over of @dradrianharrop. There was also an account called "Belinda", that got under the skin of a couple of troons and their allies so much that they both threatened or in once case attempted suicide (@bosspuppy87 and @RobynSaysBlerg).
All these accounts targeted Twitter's Troon Colony in general and Hayden/Harrop in particular. All now suspended.
Harrop was, I recall, quite upset by @dradrianharrop because the bio had "Type 1 Dickhead", which alluded to Harrop's type 1 diabetes.
The Troon Defective Agency put the blame on various people for these accounts: Mother Farrow, Harry The Owl, Mick O'Hara (@sxsligo), and others I can't recall. At least 5 UK police forces and the Garda in Sligo have been contacted about the accounts, but the culprit(s) are still at large.
The Belinda account was very, very creepy and convincing. One deranged, auttistic Troon (bosspuppy87) was bragging about going the Leicester Pride to kick off against the TERFS, "Belinda" made a police report resulting in Norfolk Police's finest visiting the mad troon @bosspuppy87 to have words of advice and put him off going to "Pride".
