Just looked in Trash at your deleted posts and saw that you responded to your ad twice the same day that you posted it thus BTT'ing it twice within 12 hours. This is the reason that your ads are getting removed.
It is ok to answer questions that have a direct impact on the saleability of your item but you cannot post the the reply sent, send me an email, etc. responses.
While I was not the one who removed them, I see why they were removed as they are violations of the rules.
