I have asked several questions on serverfault.com, which some users have decided belong better on superuser.com (although I don't think I agree and the demarcation is not clear anyway). Now, these questions were closed as off-topic, which I can accept, I suppose, but:

 - None of them was migrated to superuser.com
 - They have been downvoted, one of them as far as -3, although comments did not suggest they were invalid, offensive, vague or otherwise inappropriate except for being relevant to another site

but what's worst of all:

 - I have now been banned from asking questions due to these questions.

I find this to be a very unfair outcome to what I think is acceptable behavior. How can I get my questions migrated and/or un-downvoted?

**Edit** More generally, if a question is closed as off-topic, with a migration target, shouldn't it just be migrated? Or allow me to migrate it?

Also, can't something be done to prevent penalizing people for asking questions in the gray area between SU and SF?



PS - Another [question](http://serverfault.com/questions/432718/avoiding-syslog-ng-noise-from-cron-jobs) of mine got closed as a dupe, although it wasn't really, adding to my low question-evaluation score.
