This is definitely not a good idea, if anything SF users are not aggressive enough in down voting poor questions and a restriction like this would only make sense if there was a real pattern of down voting simply because the question was being asked by a newcomer - that is not something I've ever noticed. 

What SF has is a definite pattern of down voting poorly constructed, rambling, off topic or otherwise defective questions and that is as it should be. That description covers all of the questions in the sample of the down-voted and closed questions of yours that I've just looked at. 

If you want to avoid downvotes then pay attention to the comments that folks have left on your questions - if you listened to even half of the advice that I've just read in comments to your questions then you would probably not get downvoted at all. 

SF is a SysAdmin site for asking professional Systems Administration questions - when you add in comments like the following you are going to get a negative reaction. If your questions were clear, concise and useful you might just get away with this but when you seem to bring nothing to the table this is a bad way to encourage your readers to upvote rather than downvote your content.

I respect sysadmins but they usually do not care what devs need and from this discussion and other my exps I can make even worse generalizations abnout their cognitive abilities. There is no point to waste the time for more complicate configurations and deployments if sysadmins cannot help/answer even with simplest/primitive questions

There is a valid question in there - it can be asked in a single, short and clear paragraph. If you did it that way it would get a more positive response.
