Today while carrying out reviews on Stack Overflow, I noticed that a user had made 23 late answer reviews. I know that the limit is 20 so I wondered how they had bypassed the limit.
After a few moments, I discovered the method they used.
The bypass of the limit is done by making use of multiple browser tabs. You simply open new tabs for every review left in the queue (skipping the review in a new tab if you have it open in another tab) and then carry out the reviews once they are all opened.
I think this should be fixed.
