Jilly is pretty much exactly like Yanderedev if he went trans.
After reading up a bit on his thread, I noticed some similarities between Jilly and Louis Gagliardi, with Lily being a slightly less slothful version of him, both of them;
-survive off e-begging and peoples generosity while offering very little in return
-pretty clearly adopted being "trans" for clout and to shield against criticism along with a wide array of other mental and physical illnesses or disabilities that come and go as it suits them
-get very MATI over the dumbest things and spend way too much time going on the internet looking to pick a fight
-have an extremely unwarranted sense of self-importance
-manipulate others for their own gain
-lie about their past constantly and obviously to garner sympathy or to make them look better then they are
-speaking of their past, every dirty little detail about them in out their because they themselves put it out their
-never really got big enough to gather a large enough group that cares about driving them off the internet, despite being terrible people
-radically far left who believe in inflicting bodily harm to anyone who disagrees with them, despite being spineless cowards when they aren't hiding behind an internet persona
-are frequently mysoginistic, racist, ect. despite using these terms to demonize others
-commission degenerate fetish art
Granted, I don't know a boat load about Yandere Dev, so I'm not sure how much of the above also applies to him as well. But I got into Louis's thread a bit when it got tagged awhile back when he was, more or less, torturing his dying cat for pity money, and the guy did come off as a lazier, dumber version of Lily. Despite sharing many of the same flaws, Jilly (love that name btw) at least puts a little effort into making content to earn money, they at least try to convince others they're trans, they at least sort of try to keep their persona semi-consistent and hide their messed up tendencies.
Louis doesn't even seem to make an effort most of the time on any of this. I could write paragraphs on this, but no one wants to read all that and, like I said, I don't know much about Yandere Dev, so maybe you're closer to the mark then I am, or maybe people like these just commonly share the same bad habits? I feel like that last bit is true.
