From your first deleted message the post state that the product by Bitman would soon be introduced but you went ahead to make a reply that you have been going through the site(well that improper for a starter)

And the second post was in a nut shell showing your appreciation. Reply's like thank you, good/great job, I love the post, I will merit or I have merited  the OP. With out really adding substantial stuff to the reply would likely be deemed unfit by mods.

Inconculsion mods delete messages that the feel is of low value and improper.
You would learn alot form this discussion about quality posting. https://bitcointalk.org/index.php?topic=2605767.0
