The following is taken from What are the review queues, and how do they work?:
The review queues (also known as review tasks) contain posts that possibly need community attention, as determined by the system or other community users. You are shown these posts, one at a time, and you "review" them. Like flagging, there are badges for this.
So, what constitutes a "review"? It depends on the queue. The queues have one consistent option, though — the "skip" option. This permanently skips the post (you won't see it in the same review queue again) and is useful if you're not sure what to do.
Each user has their own copy of the queue — if you review a post in a queue, it is not necessarily removed from that queue for other users. It gets removed for all users after a few more reviews by other users (the exact amount depends upon the queue and review action done).
Badge-hunters may be prone to falsely review posts in these queues without really considering their content. This despite there being mention of the "skip" button "if you're not sure what to do". Reviewing without actually reviewing is called robo-reviewing.
StackOverflow attempts to pro-actively perturb robo-reviewers/-reviewing by so-called review audits - tests to see whether reviewers are actually invested in the process. However, this is not active on TeX - LaTeX.
How should the community deal with robo-reviewers?
