Thank you for the reply, but I don't think you are correct. When attempting to link my coinbase account with streamtip, it required me to set up a merchant profile (which requires a valid address and SSN). Streamtip even displays a message saying you will not be able to accept tips until you have done so. Furthermore, I don't believe the page you linked is the sort of page that would display if you attempted to tip bitcoins through streamtip. I could be wrong, though.
For instance, I already have a coinbase account with email and name, and streamtip will not allow tips to go through on https://streamtip.com/t/tinfoilhatguy . It actually gives an error message informing me that I need to fill out my merchant profile.
