Should I mark my account as mature?

Hi! So I don't post any NSFW things nor do I ever talk about any NSFW subjects however one of the subreddits I'm part of (r/silverwolfmains) is tagged (wrongly) as NSFW and I recently posted something there (an analysis, not something NSFW) so my account was marked as mature. However I deleted the marking since I don't do anything NSFW.

I'd much prefer not having it marked as NSFW if possible, so can I leave it as is or do I have to mark it or else my account will receive a ban?

Thank you very much!
