I only look up licensing information - if there have been complaints and such about any new T I may see. And then I simply ask them directly what I want to know - what's their training, etc.
I think most people here find excuses for poor behavior (stalker-ish) and say we just did it because of X, Y, Z. If the situation were reversed, and T googled/facebooked/etc the client, the board is outraged by such unprofessionalism. Yet the client has no accountability. Tsk tsk. I don't agree. It's creepy to me.
