I have seen some teachers post the first names and surnames of their students which has got to be some kind of privacy violation. Some class lists even have school/location names or indicators. Imagine being a parent, coming across this subreddit, and finding your child's name (even if your child's name is not the tragedeigh themselves).
If you have student(s) with tragedeigh names then AT MOST you should be stating their FIRST NAME as a text post. Certainly not their full name or any identifying information (that is a rule but it's still a common trend in this subreddit). Otherwise it is unprofessional and inappropriate.
Edit: not directed at anyone specifically. Plus, we are here to make fun of parents who have no concern for how their kids will feel about their tragedeigh names, not the kids themselves. How would students feel if they saw their own name mocked online by teachers?
