I think stuff like that is an offshoot of cuck fetishism, like just instead of being a straight dude that gets off to Jamal raw dogging your wife/girlfriend, it involves the submissive male being sissified and 'exterminated' as it were by becoming a bottom bitch for Jamal. Because we see almost constantly with cuck fetishism that there's an element of racial fetishism, the idea of this 'superior' race dominating your 'inferior' race by fucking your races women, a lot of these more degenerate fetishes overlap, like here you have mentions of hypno fetish, racial fetish, the more basic sissy or trap type stuff.
Plus since it seems most sissies online are submissive white men it stands to reason that they'd get off to stuff like being BLACKED.
So in other words, humiliation fetish.
There might be another partial explanation. A overlap with the online partner sharing community (pictures and videoes, mostly of unsuspecting people known by the sharer). Some of them get their kicks from being humiliated (being forced to share pictures by losing games and wagers, in the community they are called cucks), and some get it from humiliating their partner (gets off on the shared person being humiliated or sexualised without their consent, in the community sharers and bulls). These communities have a lot of shitty content. Producing things like webslut cards, photoshop makeup, magazines (yes, really) and other shit. They also have a lot of games. Where people are "coerced" into posting stuff they shouldn't while being horny. Either by so called dice games, like games (if so many views, shares, favourite or whatever metric is available happens, the cuck post something new) or risk games (posting pictures that gets deleted in an amount of time. So the cuck "hopes" that nobody will save it.) The latter is especially worthwhile to mention as they really use a lot of the same style as sissification groups.
The reason why this is relevant for this thread is that content of sissyfication is not only quite similar to our above mentioned cucks in style and wording, but also in outlets. There seems to be at least some knowledge sharing between the groups, if not a direct overlap in members. Most of the actual work happens in secret rooms, but some of it gets posted to other sites. Tumblr was the main outlet , but imagefap and xhamster has taken over the mantle. Point being, there might be more than one source for sissification. With the Hypno community stemming from classic gay fetish, while some parts of the "I am now a muslim fuck hole who is being forced to do this"-perverts might come from the sharing community.
If this theory is correct, we might have discovered a new group of people letting their fetish ruin their lives just like AGP's. Hetero or bi people who train themselves to only get aroused if they get humiliated through posting pictures/information on the net. Spiraling further and further into life-ruining decisions. Some are so into the humiliation that they post links to remote access to their computers. Doxing both themselves and everybody else in the process. In that case, what we are looking at in this thread is only the tip of the ice-berg. Whatever is overflowing from the imig rooms, cf chatwifes and private forums. We already know that fetish can get a man to cut off his dick, so it doesn't really seem like that much of a stretch.
