Nobody cares when someone tries to preemptively qualify incoming advice. It’s an open forum. Everyone will just ignore your criteria because you admittedly don’t know much about this. If you gave us a reason that didn’t vibe as “I think I know more than I do” I bet people would consider not chiming in.

What a normal person does is simple: just ignore the advice that they don’t value.
