I deemed your comment to be fairly offensive, you move on from making assumptions to saying that anyone that failed to think the way you did is mentally challenged.
Also, moving on to calling users sped is not tolerated here. Same goes for moving off-topic. Read the comment & general rules. It won't be left at a simple comment removal next time.
Makiavel, since you were obviously on the comment section for Prison School, can I ask why you didn't also remove/add spoiler tags to all the comments containing plot details, larger images, all videos/gifs and Posts not related directly to the manga, all of which are on practically every page and specifically listed in the Comment Sections' Rules and Guidelines as being violations?
It's one thing asking people to follow rules, it's quite another asking people to be mind readers and know which rules are going to be enforced and which ones aren't, you know. This site has a comment section that's like a lawless wild west show, and you're going to pick and choose who gets dunned and who doesn't?
