There is a style of hedonistic lifestyle/culture that usually comes with an anime profile picture and pronouns in the twitter bio. If that is someone's true "form" then go for it, but when its fake yuck.
Gratuitous anime pictures are also common in 4chan tech culture, where folks just don't pay much attention to Twitter or to the pronouns fad. So you can see that either way, it just suggests a kind of non-serious/poser hedonism all around. BBS/early web culture was a lot more focused than that.
