You have received your SBD back with the message that you are blacklisted and a warning that future transfers won't be refunded.
So don't act as if smartsteem withholds any of your funds.
Now, your linked post is low quality and smartsteem won't support 2 sentence posts.
How do I know that you do not support 2 sentence posts before blacklisting? You should give a warning. Blacklisting should be done only when somebody neglect your warning and do it again. Before blacklisting, I did not know, otherwise I would have used only log posts. (So, you are assessing the quality of posts from the length of post. Actually, shorter posts have more quality because it conveys the full idea without wasting the time of readers. Anyway, I am not questioning your policy.) In addition, when you blacklist someone first time, it should be for a small time period. If he violates your rule again, then only you should put a permanent ban. This is my opinion. I feel that everybody will be having this opinion.
It is very easy to make long posts. Just copy a long post from somewhere and make some changes by inserting some comma or full stops, or removing some words or adding some gaps so that Cheetah will not catch you. But long post will waste the time of readers. So, Usually, I read a full article and make it very concise in a few sentence and post it. Those who read my article will get the message by spending only 10 seconds time. That is called quality. Quality cannot be assessed from the length of the post.
