[omni-m00gle]

Here's my theory on what happened.

Stefan got an email from anna to update the account.

Without thinking, as usual (good old Stefan), he updated it. Not noticing that it said Fidel Castro.

Or, rather, he noticed, but didn't care.

Then, he sees marle's signature.

His hatred towards people who bring up Hitler comes forth, considering the countless times he's been called Hitler, Nazi, or just a German bastard or something.

He figures that's one good reason to internet-stab anna. Then, he notices the account name.

Stefan: ACH! MEIN ACCOUNT NAMEN!

Boom. Two "good reasons" to be mean.

I love you Stefan.
