I'm trying to register at http://forum.subsonic.org/forum/ucp.php?mode=register but all IPs I've tried are banned.

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 chosen.
  3. Your ISP is well-known for a lot of spamming customers and is not fighting against spammers enough.

I've already tried my home ISP, mobile ISP, different Tor nodes, Opera Turbo, different free VPNs, different free proxies.

How can I register there?

(I've thought about asking somebody from another country to register there for me but I still hope to do that on my own.)

  • Are you trying the same username when you switch ISPs, Tor nodes, VPNs, etc? If so, I suspect they check to see if the username previously used a banned IP, and then they add your new IP to the banned list. Try a new IP and a new username. Feb 24 '15 at 16:28
  • @pacoverflow I've finally registered there through my friend's ISP but nevertheless I've tried through Opera Turbo with different username - unsuccessfully.
