Reports Types

Report Reason	Description
Offensive Username/Biography/Avatar	If you wonder whether or not that stuff would fall under the rule, it most likely already does, but generally, apply some common sense. No ethnic/racial/explicit sexual stuff(Though not to a puritan degree) or other obvious suspects. Clever workarounds also don't count, if the intent stays obvious. Seriously, just don't.
Other	A reason that doesn't appear in the pre-selected options, but breaks another rule. You should be clear on what rule is broken and make a good case. Usually, if there isn't a fixed reason, it tends to not be reportable, so really think about it if you intend to use this category
Spambot	If a different account acts suspiciously, like promoting services or websites first thing and speak like they are pitching something, they are likely a spambot and should be reported as such.
