I didn't see a fandom as cringe and disturbed as Diabolik Lovers's, between the y/n bimbo type ocs, the problematic contents that are considered as kinky and the glorification of a stupid blonde stereotype main character, I'm clearly not surprised about the fact the fandom is slowly dying. It's pointless to run a blog only to satisfy the cringe fetishization of such problematic fictional characters and what they represent. Regarding the confessions about Yui, it sounds more like p3d0philia, considering how the character is designed to look child-like, in refering to nymphette-coquette-lolita aesthetic. Not even to mention her physical stature is clearly like a child with no feminine forms and no boobs. You won't tell me some weirdos are aroused by Yui. I wish you don't willingly collaborate with mentally unstable girls/guys in order to feed their pervertions through your blog. That's your responsibility to not allow that, since you are an adult as well.
I'm not even gonna start to argue with someone who clearly has a problem with Diabolik Lovers in general. If you don't like the franchise, stay away from it. Leave the people who enjoy it alone. Simple as that.
