Do you ever put disclaimers on your work?

If something you're writing has content that's morally questionable (or worse), do you ever put a disclaimer on it about not supporting it IRL/the ways that it's bad? IE like on a fic with a student/teacher pairing, etc.

I started doing that recently after seeing it on another fic so I'm curious if anyone else does it.

Edit: I primarily mean for the benefit of younger readers who ignore the age warnings, etc. Like a 17 year old reading a student/teacher fic or a teenager reading a fic where an 18~ year old is with a 30+ year old, etc.

Edit 2: Based on these comments, I'm gonna leave the disclaimer in the end notes only.
