Bots sometimes have trouble with this (name syncing). They use lists of registered handles, and lists of emails. If the first email they try is already blocked, they often try a 2nd which doesn't match.
Other times they lose track of each other, and reply improperly to previous leading posts. ie - spamhandle asks a question. Then a while later, the same handle enthusiastically answers the question, recommending Snake Oil Cream. And states they are glad to help.
I guess the sweatshops aren't paying the coding kids enough.
