I don't think that creating auto email verifier will work in this case. It shouldn't be so much difficult to create a tool which clicks every single link in email, but most of use use DIFFERENT email providers and clients.
For example, you may use Gmail, I may use Live Mail, someone else may use another webmail provider, and many other Social Bookmarks Submitter users may use NOT webmail systems (but POP3 tools).
I'm not an experienced programmer, but I think that you should create HUNDREDS (if not thousands) rules for this tool.
P.S. I don't mind clicking activation links manually. Takes about a minute to click all of them.
