@shitpostalotl @r0se i think i'd personally mind that less, but i wouldn't at all rule out someone else being uncomfy about that.
"just depends" feels kinda reductive, but you're right that it is ultimately subjective. functionally, it's just an avatar- if it conveys what you want people to perceive you as, it performs the task well. we don't necessarily have hard and fast rules for what constitutes an "appropriate" avatar, but we can draw lines if and when we take issue with things. that's usually how building social rules works.
hell, i'm sure my current avatar's looming demeanour might extend beyond someone's personal threshold- if that means they don't want to interact with me, that's okay. they'd probably have a hard time conveying that my avatar is explicitly pornographic and shouldn't be shown in public spaces, but they are well within their right to block me indiscriminately and move on.
