There’s some discussion in our forum right now about content disputes and the specifics of our Terms of Service. It seems there is room in our Terms for folks to debate the difference between an update and an insult. There is some confusion surrounding our official policy with regard to taking action.
Some people think we should ban one person if another person is unhappy with the content—or more specifically, if they personally define that content as “harrassment.” In the case being discussed, we didn’t perceive a violation of our Terms after a careful review.
This speaks to our larger stance that Twitter is a communication utility, not a mediator of content. For those who are interested in this debate, please note that we are engaged in editing our ToS so it more clearly states the scenarios in which we will take action. The revised ToS will reflect this earlier statement of our policy on abuse.
