Children, stop writing ahh instead of ass I beg you

This shit drives me up the wall even more than "unalive"
You can't stop people saying slurs but an entire generation will subconsciously alter their entire vocabulary because they grew up on corporate platforms with very heavily moderated text chats and comment sections and they ended up internalising the filters 
Edit: I was not aware of the AAVE origins of "ahh" which pushes it more towards the territory of legit slang. Still, I stand by my general point about automated moderation influencing language being bad
That kinda has to do more with brain plasticity than the old acronyms being better or worse though. We don't learn as easily as we used to when we were younger so we forget what the acronyms mean.
