Given that you used to run one there really isn't much you cant do now. Austria has lots of organizations that got your back. If you ever end up in trouble and don't know who to ask for help just mail the Tor Project directly they know who you want to talk to.
It's still a legal problem as much as running an exit node is, they just can't easily figure out that you did anything because of how Tor works. You couldn't even confess to anything either if you wanted to.
