I always keep track of the submission queue to see what neat new hacks, translations or reviews might be coming up to the database.
However, as of late I've been noticing that there are some review entries that just plain out phase out and end up not appearing at all, simply vanishing from the submission queue, but not being accepted to the hack page that they submitted the review for. Some hack and translation entries have been following the same steps, but for those I can understand why they might not appear (being rejected for lack of info, wrong hashes, wrong images, etc.).
But for reviews, I find it weird that they simply end up not appearing.
My question is, what is going on with the reviews that have been submitted but end up not appearing at all?
What is the reasoning behind this? Not to bash or anything, I'm just curious as to what is the process for these and if there are any rules that might affect the reviews being accepted.
