421 Your IP address is not welcome here. Goodbye

I keep getting this message when trying to connect to a certain FTP site[others are fine] and it's really irking me. I need some way to get around it. I need for my IP address to be invisible or something maybe, I dunno. I've tried proxies, but they often don't work, or if they do, need to reconnect constantly. Is there a better way?
