The phrase that springs to mind is 'hoist by your own petard'.
According to Wootton social media is an evil, virtual witch-hunting tool now. He's a poor, badly done-to, ill-treated victim - now.
It's a different story when he's using the same platforms to hound others. Lily Allen claims on Twitter he had her in his sights for 15 years, meticulously documenting every twist and turn of her substance addiction. Other names she mentions in that same context are Peaches Geldof, Caroline Flack and Amy Winehouse. Wootton has been involved in acrimonious litigation on numerous occasions - including with Flack's former fiance. He's relentlessly pursued Meghan Markle.
On Schofield and Edwards I have no comment to make, since their conduct has - probably rightly - seen their prior employment terminated and rendered them unemployable. The broadcasting establishment at last seems to have understood that they cannot get away with rugsweeping that behaviour any longer. It's been a long time coming.
I'm not commenting on particular allegations against Wootton. Criminal ones need to be dealt with by due process - if his actions fall short of criminal but are still unacceptable as with Schofield, he will likely still fall on his professional sword for it. But that's an aside. At no point has Wootton ever required unassailable evidence in order to pursue his vendettas against others; not that this would in any way have justified his crusades against any of these people. He's now getting a small taste of what it feels like to be on the receiving end.
Is he worthy of sympathy? Well, fuck that. You reap what you sow.
