My email address is *@example.tld

Fails a lot of validations because ‘example’ can’t possible by right eh?!

This one actually almost makes sense because of RFC 2606 [1]. It reserves the .example TLD as well as example.com, example.org, and example.net as only example domains that cannot/should not be used. Back when .com/.net/.org were "the only TLDs that matter" a blanket check for example in the second level made some sense, and/or to just assume that RFC 2606 would apply to future TLDs (despite it being quite specific in which domains it reserved).

Some second level example addresses are actually reserved and not for use. See rfc 2606.
