It's hard to concieve a case were you could be liable for anything by simply putting up code online (except for cases where you don't have the rights, e.g. copyright, to do that in the first case or including a death threat in the code) but I hope there is no place that allows you to simply state "I am not liable" to absolve you of your wrongdoings. Usually you are not liable for what other people do with your code. The German case of nor allowing to give up all your rights has another intention: In the past creators were pressured to give up certain rights which was deemed unfair. To protect the weaker party in negotiations you can't sign away some rights, e.g. allowing defecament of your work, the right to not have someone else's named as an author, or remuneration for a novel not yet envisionable use of the work.
