A random advisor could still be in the position to trick you into installing something dangerous. For instance they could work with some sort of software developer, install a backdoor and host it on the actual real hosting site, and tell you to install it. Instantly rooted. I think it should be someone you semi-trust, not some random. Not someone CLOSE to you per say, but someone that you have known for a while, has a history in the scene, and you are pretty confident they are not LE. Hope this helps.
