That's bad practice in my opinion. Such nodes could also be border points for universites or large businesses or ISPs. Plus exit points change like the hours on a clock - people drop in and drop off the network on a whim, and many using dymanic DNS. So blocking Tor nodes is very iffy, and could wind up blocking a bunch of legitimate contributors.
I think you're somewhat overstating how frequently the exit node list changes. Nodes may change regularly, but there are a lot of IPs that have been steady Tor exit nodes for a long time, no?
In any case, it should be noted that it's Foundation policy to block all open proxies, including Tor exit nodes. The harm outweighs the benefit when it comes to trying to stop vandalism.
