Check out this Profile, which looks fake to me:
When I get the email from LinkedIn, I can “accept the invitation.”
If I want to check out the person’s page, I can “Accept invitation.”
But what if I don’t want to?
I would LOVE a link to IGNORE from the email AND from the Profile page, when I’m checking it out. Otherwise it is too easy for me to be lazy and accept, or to just not do anything.
