I mostly mean the human side of it. Even without something like that the alias part was fine, it was not remembering which one I used when asked in person. Or family members being unable to remember my email because the answer wasn't the same one time.

I understand why the idea is appealing, I'm just putting it out there for anyone else reading that the human element is a cost I hadn't considered when I started. Personally I don't have enough of a spam problem to warrant committing to it.
