Is there a Stack Exchange section or site for issue(s) solving and with no reputation limit on question's acceptance, so people could ask about rare problems being watched or reviewed?
E.g., "What are the reasons for iwatch, on Linux distribution (Ubuntu), notifying about create events listing a "//.ismount-test-file", that is not to be found on this root file system root directory?"
From my experience, such a question (given, its not an absolute suitable example of a rare content question) will not get very much interest and maybe even negative or no upvoting, because only a few will have experience with this particular difficulty or problem or even understand what could be a cause for or reasoning for this tool's output? (Trying to solve this question's difficulty in comments ended with no explanation or solution, so far. That's comprehensible, because SE Meta is no expert site therefore and it seems that references for solving were not attempted or successful. This, describing experiences and reality somewhat supporting following suggestion for feature-request:)
I would recommend creating a (or an experimental testing phase) Stack Exchange site, with asking questions for being solved for users that did reach (a state of 'question on hold' or) question ban (for several reasons). Maybe this site is called (with a supportive tone) Stack RareContentCollector and limited to one additional question once a week accessible for users with question ban from every Stack Exchange site. I don't see this initial attempt for another Stack Exchange site being an exact duplicate to suggested question/answer for less strict rules on each Stack Exchange site or another Stack Exchange site for 'questions on hold', but for (also) question banned users with a weekly cadence for a chance of asking (for to improve or solve difficulties). We agree on thinking that site being a pool from different topics (SE sites) and interest areas meeting on that site for just asking a question for to solve difficulties. It's close in meaning and suggestions, but suggested duplicate doesn't consider the problem of question banned users (what includes the possibility, that a question ban can be caused from a summary of years old questions, off-topic starter questions, 'ahead of mainstream' or rare content questions (therefore possibly no answers), that are potentially more inclined to neutral or even negative voting, because of lacking a wider identification base with voters or deleted by Community bot and therefore hidden from voting and review.)
Stack Exchange Meta Tour advised:
"Be part of the community that decides how the sites work" "Ask about... Specific issues with the software that powers the Stack Exchange network Real problems or questions that you’ve encountered using this software" "Any question that has to do with the Stack Exchange family of communities is fair game."
Just a side note to a now recognized limitation:
"On posts tagged feature-request, voting can indicate agreement or disagreement with the proposed change rather than just the quality or usefulness of the post itself."
If the feature-request tag would be removed, will votings showing disagreement/agreement be adjusted, because there's a change in purpose for voting?
Thanks for contribution to brainstorming on that difficulty.
