I have received the warning that I may be blocked from asking on SuperUser SE.

I searched the Meta Stack Exchange help site, and also questions already asking about it, to find out what is the reason for my particular warning. I concluded that it is mostly likely a big number of my questions that didn't receive any votes.

This answer suggests that deleting questions after 30 days of being asked won't count against the ban. Over time I have got acquainted with the whole SE network better. So now I see that when I joined the site I asked many marginally good questions, as well as marginally on topic - mostly about two topics that I was dealing with at that moment.

Some of the questions mentioned have no answers, but many of them have one.
Would deleting these old questions be a good idea to help me get out of the "warning zone" ?
