My question was put on hold as unclear. I see a number of issues in this:
No intent was made to clarify the question via comments: it was just shut up. I consider it rude and unhelpful.
No reason was provided as to what specifically was unclear in my question and why the judges thought that it was unclear, put aside any hint on how I could improve the question to make it clearer. I consider it against common practice: it's the burden of accuser to give a reason for "jailing" a question, not the burden of the OP.
No way of responding or requesting re-consideration. I edited the question and added a comment about it, as requested in the standard "put on hold" notification, but I guess the closers do not get a notification when I update my question, so they don't unblock the question no matter now much detail I add to it.
Absurdly counter-productive. Other people do understand the question and do have good answers to it, but since somebody decided there should not be good answers to this question (or did not know the answer) people who do know the right answer cannot post it. What's the benefit of preventing others from giving answer to a question?
Time lost. Even if there is an option for users (with sufficient reputation) to request re-opening, this is unlikely to happen because while the question is on hold time passes and it fades out of the list of recent questions; generally a question not answered in the first half an hour attracts very few new visitors. Plus not all users know of the "re-open" link.
I do understand that some questions must be censored out -- say, those that promote racial hatred, those that "have attracted many low-quality answers," or those that are clearly off-topic. But I consider that such censorship should be applied with extreme causion instead of being common practice of treating questions with suboptimal wording (according to somebody's feeling).
I suggest to discuss it as
technical issue 1: the OP is not notified (via standard SE notifications) of the question put on hold (or suggested for putting on hold), and keeps waiting for the answer until it's too late.
technical issue 2: the closers are not notified of the OP editing the answer and requesting re-consideration.
ethical issue 1: the practice of blocking a question without ever making a single comment to it is extremely unhelpful to the OP.
ethical issue 2: forcefully preventing other users from answering a legitimate question to which they have a good answer does not make sense.
