One reason also why they removed your post.was you posted on the wrong section. If you posted on the right section with the right content then your post survive....
Last post was regarding bitcoin in bitcoin discussion thread. I think this is not offtop

Anyway I hope for some comments from moderators. At least why any messages are sent in case of post removing.
In other case topic author do not even know what is wrong and will not know for future why his post are removed...
