Add reference to disclaimer to top of Merchants page
This recent post brought to light that the services listed are not necessarily verified as authentic.
The merchants page should have a disclaimer that the services listed accept XMR, but it is not known if they are legitimate.
EDIT: Best to put it, or an excerpt, at the top so it's the first thing people see. That way when they look at the list they are (hopefully) in the right mindset.
