I had a question (Does ARP work in the presence of MAC Masquerading) which got two up-votes and one following-star within two hours of its posting (indicating that people seem to have understood and liked the question itself) before being put on hold by a single vote from "RonMaupin", who appears to have spent very little time thinking through the problem.
In that time, another commenter understood the problem correctly and found the answer, but was unable to post it because the question was put on hold.
I have several comments regarding this:
Why can one person do this so quickly?
The very person who's likely to have the rep required to do this can also be the kind of person who succeeds by quantity instead of quality. Therefore, anything not trivially-answerable by this person pointless to ask because they won't spend time to understand and will instead vote-to-hold or vote-to-close.
Do you want only trivially-answerable questions?
To continue, if your goal is to only have trivially-answerable questions posed across the Stack Exchange sites, this pattern works. However, as somebody who works at the edges of many domains and sometimes faces nuanced or complicated questions, this makes the SE sites worthless; I cannot ask a complicated question without somebody like Ron coming by and closing the question or putting it on hold.
If I cannot get anything from this, why would I put anything into this?
If, seemingly no matter what I do, my questions are always worthy of somebody like Ron closing them, why would I put energy into any SE site? I look at the current questions on the front page and can easily answer about half of them. However, I'm soured enough against SE because of these people that I just don't care enough to spend the effort to do so.
