I got review banned for 7 days on March 3rd, 2014. I have the habit to click on Review whenever I am on Stack Overflow's page. Yesterday it was showing me the following regular message
You have failed too many recent review audits – looks like you might need a break. Come back in 4 days to continue reviewing.
So there were 4 days left of my review ban. But this morning when I click on the Review link, it allowed me to perform a review. You can see my review history
I double checked all the reviews, there isn't any failure in today's reviews.
Now again when I click on review again it shows me same message as before, but with a 3 day warning
You have failed too many recent review audits – looks like you might need a break. Come back in 3 days to continue reviewing.
First I thought that it was because of some of my helpful flags that my review ban is lifted automatically by the system. But now I think that this is a bug in the system. It shouldn't allow me to review for the next 3 days.
Update This issue is re-produced with me just before few minutes. I have notice one thing that this happens only one time, meaning after ban this happens one time only and once it happens it doesnt happens again till the ban period is over.
