I really am not a big fan of the "fill out this form and then we'll let you see this next page" types of hurdles that a lot of websites put up, with dozens of mandatory fields to fill out. So, I try to meet them half way by filling in things like "please don't call" for name, phone #, etc. Don't want them to waste their time reaching out to me when it's not a worthwhile investment of their resources.
Of course, the reason that organizations choose to require all that information is so that they can try to roboticize as much of the "relationship" process as possible, which is a fool's errand. Relationships can't be automated.
That said, many continue to try. Hence the email I just received that addressed me as Mr. Please-Don't-Call. That cracked me up.
