Moderators make recommendations on what content to remove from the site. They can temporarily hide content that violates our Terms of Service, and the admins then decide if the content should remain on the site or if it should be removed.
Moderators can Hide Opinions and Comments. Super Moderators can Hide Questions, Question Updates, Takes, Opinions, and Comments and correct topics. Uber Moderators can Hide Questions, Question Updates, Takes, Opinions, and Comments and correct topics. UberMods can also temporarily freeze member accounts in cases of consistent infringement.
You are judged on your success ratio. If you maintain a high percentage of reports to removals you will maintain your mod status and looked at to be moved up in the mod ranks. You have to become familiar with the rules. Since you got the email from the site that means all you have to do is respond and they will send you an email with details of what to do next.
