Euphemism is already common, particularly when discussing sensitive topics like the cycle of life, bodily functions, etc. You are probably okay with many existing euphemisms because they are familiar. This really isn't a social media thing, newspaper obituaries also use euphemisms for death. e.g. "passed away", "departed", "eternal rest", etc.

Yes, because that euphemistic language is there to lighten the blow. "unalive" is an attempt to bypass a social media filter and speaks to the shift in how and why words enter our lexicon.

Are you against profanity filters? What's the difference?

[SketchySeaBeast]

Well, because "suicide" isn't profane. It might be considered a pseudo-profanity, but people don't stop saying swearing because of profanity filters. This is an instance where the filter is feeding back into the zeitgeist.
