Well - generally you don't want to really delete posts unless needed.
Several of my questions attracted griefer who bombarded the comments with knit picks
Well - moderators can see deleted posts. The deleted posts were off topic, closed and the comments advised they were and why. They seem to have been ignored.
Is there another way to bring my rating up!
Feels like the wrong thing to take away from the situation
Looking at your posts, you essentially tried to ask the same question about IOT, 3 different ways and that pushed you into a question ban. Rather than taking the comments as nit picks - taking into consideration the comments on the first attempt would have saved you from a suspension.
We'd rather help folks avoid question bans in the first place but I don't see the current state of the questions being fixable in a way to lift the bans, which are automatic.
I think the important thing here is to understand those comments are there to help, and to better familiarise yourself with the site as a whole. Quality content will help a lot - good answers (and take your time with those - we have answer bans too, and sometimes folks overeager to get a question ban lifted get those) and other positive contributions help somewhat. There's also generally an opportunity to ask questions about 3 months after a question ban, and its worth asking yourself how best to use it.
If you get these things, then it should be possible to pull yourself out of a question ban.
