Twitter has updated its guidelines so that it's now easier for users to figure out what actions will lead to them being banned. A new version of the "Twitter Rules" went out on Friday. In it, the company fleshes out its abuse and suspension-related sections.
Along with giving people a better understanding of what they must avoid doing to not be banned, the network will email those who've been suspended with an explanation. A lot of people were previously suspended with no explanation.
None of these updates actually change Twitter's internal policies, but they should improve its implementation of them. Because it frequently used vague policies, users couldn't really tell what would count as inappropriate behavior.
It's updated its language pertaining to graphic, adult, self-harm, and violent content, among other things.
