What problem? They filter ICMP requests, so traceroute doesn't work. That's not really a problem.
Actually, traceroute uses UDP probe packets by default and more and more hosts filter them out. I have a workaround for that:
traceroute -I risingstarmbc.com
This uses ICMP Echo packets instead, which are more likely to get through. However, you either need to be root for that, or SUID on /bin /traceroute, which is what I did because I'm the only person using this machine; I'd not do it on a production box just on general principles. In fact, I have an alias for it in .bashrc:
alias tracert=traceroute -I
which works fine. (On a production box, I'd put the alias in root's .bashrc and use su -c to invoke it.)
