Omitting letters in their username, getting the domain wrong by omitting or mutating letters, commas instead of periods, spaces, and more. Some, such as commas and spaces are easy to catch, but mutations in the username are pretty much impossible to catch.
Without digging through my records I can't be more specific, but in general I was horrified at how many can't actually spell their own names correctly. Seriously, one person typed jojn.dpe instead of john.doe (name deliberately changed to protect the user). Sometimes it's possible to guess the correct username/domain, but sometimes it simply isn't.
