Can not register to forum - blacklisted, spamer ???

          Dear All,
     I don't know where to write but I can register to
http://forums.debian.net because I have the following message:

An entry on the blacklist may have several reasons:
1. You are a well-known spammer.
2. Last time a well-known spammer was using the dynamic IP address which
you got from your ISP (Internet Service Provider), your e-mail address or
the username you have choosen.
3. Your ISP is well-known for a lot of spamming customers and is not
fighting against spammers enough.

     I am Debian user for nearly 10 years and GNU/Linux user since 2006.

     Since I can not change my home and mobile provider (have the same
message for both) is there any way for me to register to debian forum?

     Thanks in advance.
     LoMi
