The risk is only involved if you're running an exit node, which you don't have to. My server is running a middle node for almost two years (~0.3-0.4% chance you'll go through it) without a slightest inconvenience. I've put a daily cap on the bandwidth so that I can use the server for other purposes without increasing my server bill. As a result, I'm basically donating bandwidth that'd otherwise be wasted.
