The question "Why is processing a sorted array faster than processing an unsorted array?" is fairly old at this point and doesn't really need additional contributions.
For whatever reason, it seems to attract pointless answers that add nothing but noise. I can only assume people see the question is highly viewed and have a misguided desire to add their name to it. Heck, the latest "answer" is literally just splicing together two existing answers: https://stackoverflow.com/a/69893073/87234.
The result is I get a low but present rate of notifications about a "new answer" on this question. It's not unbearable, but it's gotten sufficiently annoying that I'm posting here. Without fail each new answer is some garbage contribution (often literally just a wrong answer) or some attempt to copy the existing answers by rearranging the words.
None of these need to exist. Many of them never get deleted and just hang around adding trash to the site.
Do we have statistics on if the protection is sufficiently high? How many answers get added to protected questions that become downvoted or deleted? Can we suspend users that abuse this? Can this question just be locked?
I recognize this may be unique to a small set of highly-viewed questions. I just request the protection threshold be raised to something actually meaningful. Beyond the apparently minimal "is this person still breathing" level achievable by smashing your face on a keyboard.
