URL BLOCKED

YO guys!

I am not quite sure if this has already been posted! Please help!

The ISP here blocks some URL like web pages that lets you preview a yahoo user profiles (i.e. http://profiles.yahoo.com/user123) and others. I had already written a request to them to unblock it but I guess they will never do it anyway for any reason. My question is this:

1. For enlightenment, is there any other way that this issue could be resolved and access the blocked URL?
2. If there is, what tools I could use to do it and is it legal?

As far as I could imagine, maybe it is a better idea for the ISP to block the bad websites instead (like sites detected with malicious codes or promote ADWARE/SPYWARE, sort of stuffs like that! At least they could HELP avoiding thousands of surfers fall on such malicious attacks).

Thanks

YO!
