Since my posts were deleted twice, I also wanted to figure our why it happened. And I found that my post was too short or unrelevant. That is what I got to know from my experience. I think if we learn more with more patience and are careful about our posting, then we can get reach to next level.
Usually, the reason for the posts removal is precisely the unqualified author and irrelevant comment on his part (this may be due to the fact that the information published by the author is fake, non-argumentative, or has already been expressed many times in this topic). The size (length) of a post doesn`t play a special role (exceptions are posts like "hello", "me too", "support", "+1"). A constructive and interesting idea can be expressed with a couple of phrases, so your posts were hardly deleted due to the fact that they were too short (on the contrary, too long posts from newbies suspicions). The main reason was their irrelevance, as you correctly noted. Try to write the information are sure about and which will be useful to other participants.
