They could undo a lot of good will (Iran elections, etc) just by censoring this one thing.

Regardless of the root cause, I think twitter just took one to the face. This looks pretty bad, even if they come out and say "oh, our spamfilter system malfunctioned."

I sympathise, though. I've run email spamfilters before, and boy, people get /pissed/ when false positives happen.
