It's very simple. You did not read the EE rules which are located at the top of every EE forum. Bumping your ad before 72hrs or the 4th page is a BTT (Back to top or Bump to top).
You can answer ?s that directly relate to the sell of your item. But posting email sent or Im sent as a reply to someones ? it a violation.
There are thousands of members here. Many bump their ads early so we just trash them. We do not have time to write IMs or emails to all of them. It gets really really old saying the same thing over and over again because people did not take the time to read the rules. When people bump their ads early, it knocks someone else's ad off the first page.
Hope this helps.
