It is already the case that accusers need more proof than "it came
from your computer." As more and more computers on the net are running
vulnerable operating systems, it is becoming almost the norm to tell
somebody "hey, your computer is compromised" rather than to accuse them
of actually doing the activity.
So people already need more evidence, such as finding the bad files on
your computer, before they can believe that you're doing bad things. Tor
doesn't change the situation as much as you might think.

You're right that this depends on laws which may differ from country to
country. If it is the case that operating a Tor server isn't breaking
any laws, then it would seem that no, we are not required to do anything.
We have four broad approaches to combatting the abuse complaints issue:
1) Educate people generally. Explain about the good uses of Tor, and get
people to understand that anonymity has many positive social values. Also
get them to understand that the abuses they're seeing can happen many
other ways, and Tor isn't really introducing new classes of abuse.
2) Educate people specifically. When we find a site like wikipedia
that has decided allowing its users to retain privacy is not worth the
hassle, we need to work with them to help them understand the issues,
design better authentication mechanisms, etc. We've had nice success
with this with Freenode, for example.
3) In cases where we can, we should take technological measures to limit
the abuse potential in Tor. For example, our default exit policy rejects
port 25, which could be used to draw bad attention to Tor servers.
4) We must become a larger network, and become more mainstream. Google
produces plenty of abuse by running Google Groups, but nobody is clamoring
to have them shut it down.
Hope this helps,
