My (least) favorite in this category is email addresses. It's astonishing how many developers screw this up by trying to validate an email address by some means other than sending a message to it.
The problem is that if you send a message just blindly, you can be tricked into sending spam to millions of addresses. I do one thing that prevents that, but does violate the standard, I verify there's only 1 '@' in the address.. this technically prevents people with '@'s in their name, but they probably find it impossible to do anything with that address anyway.
