Starting the other month, review audit checks were added to the review queues. These were added after disturbing "rubber stamping" was noticed, which resulted in poor quality content being upvoted constantly.
These audit checks are questions that are known to be high-quality, or known to be low-quality. It is expected that you, as a reviewer, are able to discern the difference between high quality, average quality, and low quality content, and are taking an appropriate action.
That is, you should be upvoting great content, leaving average content alone (or suggesting improvements), and helping to improve, flag or otherwise help with the moderation of low-quality content.
When you pick the wrong answer during one of these audits, the system should give you feedback on what went wrong and how to improve your actions in the future.
You have failed so many of these audits that you have been temporarily banned from the review queues.
When the ban is lifted next week, you need to either use the review queues and act like a responsible member of the community -- don't just upvote everything -- or avoid the queues completely.
