Suggestion: ban "help", "confusion", maybe "question" in titles. When a user uses these words, show the message (better ideas are appreciated):
Please avoid using word "help" in title. Instead, describe a problem you need a help with. Please check [link to how-to-ask or Why is "Can someone help me?" not an actual question?.
I don't see how "confusion" can be of any use. "Help" is trickier, since can potentially have collisions with help menu item. In this case I'd suggest checking if there is "menu" in a title. I don't think it'll happen often (the last such question I've found was 5 years ago). I can miss something, in this case please point it out.
In any case, in my experience they are completely useless words, which make titles totally uninformative, "can you help me"-level. Of course, it's easy to bypass this limitation (e.g. "he1p"); but:
- It may be good to leave a workaround for legitimate uses.
- If the uses are not legitimate, people will just downvote and go their own way.
If you have other word candidates, please suggest. I primarily suggest this for Stack Overflow (since it's the one I'm familiar with), but I expect that other sites can win from this as well.
