Yesterday there were twenty-some reopen votes, most of which were for "duplicates" where there was no change in the text. Not one was worthy of being re-opened in my opinion.
This morning, there are 44 reopen votes pending in the review queue.
There are also two re-open votes in meta right, but I did not go into them. That seems very odd.
Something odd appears to be happening. I am using the bug tag because that seems most likely, but someone should investigate this pattern in any case.
