Yup, I just ran your IP and I'm seeing a number of matches. Your ISP has one standard IP address for it's users. If you will go ahead and and try to apply again. Then post here what name you signed up with, we'll get you accepted.
Your applications were getting rejected because you show up as sharing an IP with other players, due to your ISP recycling them. In fact, your application might be rejected again, if it is seen by someone who hasn't seen this thread.
The best way to ensure it'll get through is to pop in the IRC help room as you submit your app, and tell us your handle and link us to this thread so we know to let you though. If you cannot use IRC, you might try emailling assistants@swc instead to reach most of the people who handle join requests.
I dare you to make less sense.
Are you a newbie, or do you have access to newbies?
