I can see how it looks like a weird obsession but we didn't actually find some of them - they found us. Fire came here offering information on ADF and trying to hawk his gofundme. Neph came here to throw Fire under a bus. Greta wasn't on our radar until she decided she didn't like us being mean to Fire and turned up at Null's house. Others have tried to have our hosting taken down.
When someone we've mentioned in passing kicks up what seems like a disproportionate fuss, we tend to take a closer look - and when we do we almost always find stuff which justifies them getting a thread of their own.
A few of the other troons got their threads from being screechy SJWs trying to capitalise on Gamergate. Nobody would have a clue who they were to this day had they not tried to ride that wave for pitybux/fame.
We really don't go out scouring the net for troons to mock. We don't need to.
