Difficulty in signing up

[baddeal]

I am trying to sign up on a website, but when I type in my email address I get a message that says: "Registration is not available through proxy servers." If I can't use my email address, then what do I do? Will appreciate any advice, thank you.

EMAIL REDACTED - SS

If you read the message, it said registration is not available through proxy server.
So don't use a proxy server for signup

I don't know what a "proxy server is, and do not know what I should use instead of a proxy server.
