You were not banned - if you were you would not be able to post (including this one).
Posts may be not accepted if they are NOT following FORUM RULES, that apply to everyone.
For example your posting without proper CODE TAGS is against forum rules. So you should be actually glad that this post was accepted even though it violates the rules.
You should FIX your post using "Edit" feature so the code is properly formatted as per forum rules.
So why are you treating the FORUM "that way" (not reading & following the rules)? The forum is public place (like theater or opera) where you are expected to read (or know) the rules first and follow them.
Also if you read just 10 seconds about discourse ("the introductory info" sent to every new joiner) you would know that what you assummed as ban is just a feature of Discourse that prevents people who just joined to send tons of spam. That is one of the reasons why this forum is spam-free. This forum is not Facebook or similar trash site. We have rules here, we keep site tidy, properly formatted and aesthetics are important here.
