Here is a list of common misconceptions players have about the rules of site moderation. I'll update this list when I think of more entries.

Misconception: when you ask for a specific moderator or admin to handle your case / avoid your case, they must honor that request.

Reality: when you make a request about which moderators handle your report, the mod team will often honor your request as a kindness, but they are under no obligation to do so, and if you frequently make such requests, they're unlikely to be listened to.

Misconception: it is against the rules for moderators to out your alts!

Reality: it is impolite for moderators to out your alts, and generally frowned upon, but it's not an actual rule, and sometimes moderators are actually forced to out your linked alts while reporting you or sanctioning your accounts.
