how did I break rule #6?

sorry, I just can’t remember what I commented in >>2180443 but it says I broke rule #6? how? I’ve never even used anon or a second account. begged for upvotes? impersonated staff? the heck did I do? I don’t really roleplay in the comments, just joke around sometimes with what could’ve been said in a comic. is that against the rules? I could understand screwing up and breaking rule #7, or #4, but #6? that’s for spammers, and people who post how their original character verbs the noun and saves the day.
 
I know I’m gonna be kicking myself when I find out, but I need to know how I broke the rules if I don’t wanna break them again.
