Lemmy operates more on Tumblr rules where you write out the word and people who don’t want to see it have already filtered it out in their settings. I think shorthand SA would have been fine. Hexbear rules would have you wrap the whole thing in a CW:SA spoiler and use SA in the body, which works. There’s no perfect solution. Your comment looks especially bad because your asterisks made a block of text italic (if that happens you should put a \ before them like this \*).

There was a whole thing in the Tumblrsphere apparently about zoomers, used to self-censoring from years elsewhere, bypassing the filters and reaching people who don’t like want to see that stuff, by using increasingly arcane or goofy replacements. The genie is out of the bottle now on that, and it’s just part of online communication now, but it’s interesting how we moved backwards on this.

Personally I think making readers guess the letter a in the word won’t make a difference. But if this makes you feel like you really made the world a better place for assault victims then knock yourself out.
