Nah, any advice you ever get on the internet should never be construed as legal (or medical, or <insert profession here>) advice. The whole “IANAL” and “IANYL” shit is stupid. You hired a lawyer and enter into contract with them to get proper advice. They don’t have to disclose their job/position to talk on the internet. Nor do I or any other person just to have a discussion.

I can only imagine the argument in court “He gave me advice on the internet and didn’t disclose if they were or weren’t a lawyer!”. I’m pretty sure every judge on the planet would just look at them the same way they look at Sovereign Citizens.
