By your own admission, you have reports on you. That alone will cause a number of ignored messages. I don't know how the report sites display what they know, but it wouldn't surprise me if, as well as your number it also links to your AW name and even your identity on here, if known.
Perhaps try a new phone number and see whether you get a better response.
When it comes to selecting a girl on AW, if she hasn't logged in for a while I don't bother contacting them and if they have a number displayed and not showing available today I may contact them to ask their availability. If they haven't logged on for weeks I don't bother with a message and just move on to the next one.
Edit to say, when I find someone I'm interested in, I immediately put their AW number in the search box on here. It's incredible how often I immediately loose interest.
