BLOCK QUESTIONS IN ALL CAPS
Based on this chat conversation:
I suggest Community ♦ should flag full-caps questions and answers. Perhaps full-caps questions should be blocked from even being posted at all, as too-short posts are.
(Full-caps answers should perhaps not be blocked from being posted. On programming sites and English SE, an answer might perhaps be a bit of code or a quotation in full-caps. OTOH, as noted in the comments to this question, even answers like those are probably better off with some prose added.)
