I'm always torn over that for my various accounts.
On one hand, I genuinely don't object to any pronouns being used for me, even in person. At most, if someone is being a jerk, I'd object to their motivations.
On the other hand, there are communities and instances (as well as other forums away from the fediverse) where having something there is a sign of support for those that do have pronoun preferences in a world that's really shitty towards such.
From my end of things, the act of leaving them off and accepting any that come is a statement that I don't see any gender applied to me as a negative thing. It isn't a bad thing if people think I'm a woman, a man, non binary, cis or trans.
So I end up in decision paralysis and just don't put anything there at all.
