TL;DR: I've gotten a previous account/IP address blocked from asking questions. It is pretty much the only thing I plan on using Stack Overflow for until I'm more experienced. I don't want to be a d*ck and consistently break any rules I might be breaking, but I don't understand what I'm doing wrong.
I recently had my account blocked from using the site's most basic features, essentially removing its usefulness to me on that account. I don't want to continue breaking any rules that have gotten me banned, because I don't want to offend a community of (mostly) people who are here to help others.
Why have almost all the questions I've created received a negative voting score?
I'd also like to know if people are banned solely because of downvotes, and if not, what have I done to deserve a ban?
To clarify, I have already read the FAQ and how-to-ask.html. I did this before asking any questions on my first account, and I am already complying with these.
