>I also know at least one person who decided to use a specific avatar precisely to filter out people who would decide not to interact just based on appearances alone.
I think there's a difference between just being born ugly IRL and actively choosing an ugly avatar in a game that allows a lot of customization to make it less so or even aesthetically pleasing.

To me, being born ugly wouldn't matter because we can't choose how we are born and we shouldn't mistreat people based on things they don't have control over. 
We can to some degree control or even choose our appearance on that basis, e.g. by getting scars or cosmetic treatments, and by just taking care of ourselves, the latter of which you should at least do. The ingame equivalent to that would be a game that just gives you a predefined character and maybe allows you to change what hat you are wearing (Team Fortress 2).

Actively making your ingame avatar ugly to "filter people", however, primarily signals to me that you just hate people. Not only is there the implicit pessimistic claim that most people are superficial by only caring about appearance, it's also ruthless to intentionally and for mere instrumental reasons assault people's aesthetic preferences to a degree that a lot of people would like to avoid you when you can choose not to do so.

If a person just wants to "filter people" who just treat you nicely because you look nice, they can choose the option to just use an understated avatar. 
Maybe that is what you meant by "specific avatar", but in my mind is the visual equivalent of a microphone screamer.

I would avoid someone choosing to use an intentionally ugly avatar because it shows them to be an bad person on the inside.
