He's still definitely very attractive or at least his body can be seen as very attractive
I've seen women saying the wildest shit for characters like Nanami from JJK, Ace (or really a lot of male OP characters, some even thirst for Doflamingo even though he's a terrible person, but his body is hot), Chrollo, Eren Yeager, etc.
They're just as lustful as men can be. If not even more, sometimes.
Yet I still don't think a pfp like the picture I provided should be banned because certain women can't stop themselves from gooning to Aramaki. Any way you slice it, whether or not that's your pfp, if they get tempted enough by a mere painting of him like that then chances are they'd have done it regardless.
Point is I really don't think AL Sama or anyone else is doing us a disservice by wearing pfps with boobs out, as long as they're not actively being sexualized (i.e the character is playing with them or pulling on their bra or a nipple is poking out) I don't see a reason to give a shit.
