How to stop having my answers categorized as "Nantes"?

Your QUESTIONS may get moved there less if you make your activity private.

I keep moving back the questions that OCD idiot keeps moving there but you'll have to set you profile to private because he's obviously stalking you.

I keep moving your capslock question to mental health but they keep moving it back to Nantes.

You can't stop abusive Level 7s from moving your QUESTIONS (not answers) to inappropriate subcategories, but you can move them back where they belong as often as needed. Some Level 7s who see questions out of place, will do the same (some even occasionally visit subcategories known to be dumping grounds for posts ,and do a "clean up").

There is someone who moves half the questions from Business & Finance into Dining Out. I understand getting a little pissy about a lot of the bogus and/or stupid questions, but legitimate questions get moved as well.

I'm level 7. The only time I will move a question is when it is in the wrong category (whether placed there by YA or moved by a jerk) and it's a lot of work. I have NO idea how anyone can get their jollies doing that!

EDIT: I just looked at your questions. A smarter move for anyone would be to report them instead of moving them.
