i tried to click multiple times and could not reproduce the issue, especially now that there is an "already submitted" popup window that displays if clicking more than once.the same window that works to prevent double-posts.
Also, the secondary confirmation page was removed as part of the fix put in to place. now when you click like, you get a single page that shows, and then takes you right back to the original post when you change your like status.
EDIT: See followup reply
