I am not completely sure about the risks here, but I think as the sole user on my instance they are pretty low. I think the only way content gets onto my machine is if I post it, if I interact with content on other instances, or if I create a community to which other people from other instances start posting. Despite my handle, there are some crimes I don’t do. I should be okay as long as I don’t mess with illegal content myself and moderate accordingly others’ behavior in my communities.
