Currently, as reviewers fail audits, they are [banned from review for increasing durations](https://meta.stackexchange.com/questions/174118/the-time-of-automatic-review-bans-should-be-increased-with-every-new-ban/190562#190562) (2 days, then 7, then 30). At present, this caps out at 30 days. The next time a reviewer is banned, the ban duration drops down to 2 days. Even moderators cannot hand out review bans of longer than 30 days.

Over at Stack Overflow, we have quite a few users who have been banned from review 20+ times. All of them kept coming back after being banned, since they knew they could just wait out each 30 day ban and proceed to game reviews after that. For example, I saw this in the history for one user today:

```
Jan 21  user has been banned from review    duration = 30 days
Jan 11  user has been banned from review    duration = 7 days
Jan 4   user has been banned from review    duration = 7 days
Dec 5 '15   user has been banned from review    duration = 30 days
Nov 27 '15  user has been banned from review    duration = 7 days
Nov 25 '15  user has been banned from review    duration = 2 days
Oct 21 '15  user has been banned from review    duration = 30 days
Oct 14 '15  user has been banned from review    duration = 7 days
Oct 12 '15  user has been banned from review    duration = 2 days
Sep 11 '15  user has been banned from review    duration = 30 days
Sep 3 '15   user has been banned from review    duration = 7 days
Sep 1 '15   user has been banned from review    duration = 2 days

```

Moderators receive no notification of these serial review abusers, so we have no idea what they're doing until we happen across their ban history. We've been instructed to start suspending their main account on repeated review bans, but without a way of knowing this is happening, that's a limited way of preventing them from causing damage to the site.

Therefore, I'm requesting that we allow for further escalation of the review ban duration past 30 days. This would require extending the sliding window on which bans are calculated. At present, this is 30 days, but that window could scale with the duration of the last review ban. 

I'd like to see an escalation on the order of 2 days -> 7 days -> 30 days -> 60 days -> 365 days and the ability of moderators to impose manual review bans of up to 365 days, in line with our ability to suspend accounts for up to 365 days.

Moderators can always manually remove review bans, so if someone is trapped by a series of unfortunate circumstances (bad audits, etc.), we can still override the system.

I really do think we need a better way to stop the harm that certain abusive reviewers are causing to sites when they aren't deterred by the current review ban cycle.
