They want you to call the help line, and get stuck in a queue for a long time (with the usual sh*t muzac and "your call is important"), only to talk to somebody in a completely different country with no authority to accept your feedback anyway.
I don't really understand your general safety principle. Do you use an e-mail program that doesn't show where a link goes on hover? If you can see that the link points to the expected domain, in this case stackoverflow.com, is there any reason to trust it less than if you find the link on their page after having manually typed stackoverflow.com in your browser? Or do you not click on links in general?
