Phillip, you probably need to be quiet.
Guest;
If you have had 5 consecutive applications denied, then you are certainly matching an IP with a current or past player. There are a number of possible reasons for this, including recycling of IPs by your ISP, and the connection you now have having been used by someone in the past.
What you want to do is two-fold:
1. Put something in the field for multi-accounts such as "I don't know, e-mail sent" when you submit an application. This should cause the rest of the Join team to ignore this application and not deny it as an IP match.
2. Send an e-mail to multi-accounts@swcombine.com detailing your problem and the handle that you are applying with, so that they can look into the issue properly.
