Ironically, I think it would be a good idea to auto-block titles that contain all (or most) capital letters. The obvious idea of doing this is a cheap way to attract more attention to the one's question. This is wrong and shouldn't be allowed. Most of these question will be quickly edited, wasting peoples time.
I have two possible ways we could implement this but I encourage anyone with any other ideas to edit in or answer a proposal
Auto Capitalize: If a question is submitted with an all capital title the question title should automatically switch to Capitalize formatting (every word's first letter is capitalized while the others remain lowercase, like the Right Click > Transformations > Capitalize on Macs.)
Warn OP: When submitting a question that contains an all capital title, the OP is blocked from submitting the question and a warning indicating that "The title cannot contain all capital letters.". They are not able to submit the question until it has been fixed.
This should also be added to the help center.
