You know... if you want to argue a counter-point, perhaps try arguing the point instead of relying upon insults and baseless accusations?
First: it isn't a 'conspiracy theory', and in fact I'm not even claiming there is a conspiracy. The overwhelming majority of groomers are independent actors, with little if any contact with one another. At most, one of them posts something that works on some website, and others imitate and refine.
That capacity to share strategies with strangers is hardly an unheard of behavior in homo sapiens. And to call it 'conspiracy' would make us all members of hundreds, perhaps thousands, of conspiracies.
Second: 'horny teens that know nothing about sex' is the fucking point. That's what attracts the pedophiles. Who then, again mostly independent of one another, are drawn to places where there are children to be exploited and cultivate the environment to their liking.
Another thing humans are pretty well documented in doing.
What probably happened was more one of them found an easy victim (either IRL or by stumbling across an enthusiastic consumer online) who was into this whole ABO thing in the early days, then said 'huh, I should let my buddies know'.
Not unlike what happened a few years back with people putting massive amounts of pornographic cartoons very much intentionally meant to look like ordinary young-child cartoons up on youtube using tags and presentations that would slot it into the same recommendations as Veggie Tales and My Little Pony clips.
To say nothing of the ones encouraging preteen girls to pose in bikinis.
When youtube finally caught on, they ended up deleting 'hundreds of accounts' and 'millions of videos'.
... Was that a conspiracy? No, not really. Oh, there were probably a handful of five or six-person teams involved here or there... but as a whole, no. Just groomers gonna groom.
