Okey , I accept there may have been questions which were down voted but I have been trying my level best to re-gain the reputations Infact I have 120 reputations now. I really miss askubuntu.
Here is my profile link and some screenshots.
You have 6 deleted questions, many of which have downvotes. These questions all appear to be either primarily opinion based or too broad so I don't believe undeleting them will accomplish much because you would not be able to edit them into good questions without completely changing their meaning.
Thus the only way to work out of the ban is to answer more questions with better answers. Don't go blazing away with low quality ones, take the time to test them and be sure they work, write them well, etc.
I'm afraid that is all the help I can give you.
