I think if you do something bad. Spam, offensive language, or hacking and anything else u should get black marks or demerits. Black marks and demerits would show what level of danger you are in of being banned, muted, and other things.
Like for example.. say i have 10 black marks. then i am in the danger zone or something or like medium.. and it would show on your control panel. you have ladada amount of blk marks or dermits.. i think it's a good idea. other sites use em. like runescape i used to play it. and it got me muted once.
EXAMPLE: I had a dude cuss me out on my profile once and I had to go through this LONG stage, delete comment, reload page, delete comment, reload page, etc.
You could have just locked your comments, waited for a mod to come on, report it, let them deal with the comments the dude made, and be done with it.
Just because someone does that once or twice, doesn't mean they'll always do it. *insert what Cenere said*
Just because someone made a mistake doesn't mean they should be shunned forever.
