If a question on an English-language Stack Exchange site does not contain at least one uppercase and one lowercase letter, our quality filter should reject it.

(We can make exceptions for sites which don't use a mixed-case alphabet, such as Japanese Language and Usage.)


The quality filter currently rejects neither all-uppercase nor all-lowercase posts. I've checked.

The best Stack Exchange users use mixed case. If an asker is too lazy to use their Shift key, their question tends not to be of very good quality.

Don't take my word for it. You can see proof. Sam Saffron helped me write a Stack Exchange Data Explorer query which lets you see with your very own eyes that what I am saying is true.

Single-case askers tend to ask poor-quality questions such as:

In addition, posts which use only uppercase or only lowercase — even if they aren't riddled with typos or grammatical errors — tend to be hard to read. Capitalization aids readability.

Why is this proposal not a duplicate?

This proposal is not a duplicate of the older proposal "BLOCK QUESTIONS IN ALL CAPS". This is because it also deals with all-lowercase questions.

All-lowercase questions are 50 times more common than all-caps questions. Stack Overflow gets only about 100 all-uppercase questions per year; see here. Yet it gets about 5,000 all-lowercase questions per year; see here. (These statistics are for Stack Overflow only; the rest of our network wasn't considered.)

I suspect that the older proposal was declined for two reasons:

  1. All-uppercase questions are rare.

  2. Therefore, the effort required to block all-uppercase questions is too much.

This proposal is better. For just a bit more effort, the Stack Exchange developers can get a much richer reward.


What do you think of my proposal?

Agree? Disagree? Thoughts?

PS: This idea is modified and adapted from an older idea by Stack Exchange user Gilles. My dear sir Gilles, I thank you.


There's even a chat bot which automatically detects questions with all-caps titles and alerts interested users and moderators.

  • @ShadowWizard: Random-case questions are much harder to detect programmatically. The developers could block such questions if they really wanted to, but it probably wouldn't be worth the effort. – unforgettableidSupportsMonica Aug 26 '15 at 14:10
  • @nicael: 1. The all-caps test question which I created then deleted? Ha :) – unforgettableidSupportsMonica Aug 26 '15 at 17:57
  • @nicael: 2. Is my proposal truly a duplicate, even considering the sentence of my proposal which starts with the words, "This is because it also"? – unforgettableidSupportsMonica Aug 26 '15 at 17:59

  • Yes it is duplicate no matter how you paint it. Asking to filter out or block content based on the words casing is the same. – Shadow Wizard is Ear For You Aug 26 '15 at 18:01
  • Update added a year later: Stack Overflow gets about 5,000 all-lowercase questions per year, according to a newer meta post. But even those 5,000 questions constitute nothing but "a drop in the ocean", according to some chat posts by JamesENL and Quill. Therefore, perhaps it wouldn't be worth the developers' time to configure the quality filters to catch them. – unforgettableidSupportsMonica Jul 14 '16 at 14:02
