Current guidelines are as follows Identify the user that authored or provided the Tweet, unless you are providing Tweets in an aggregate form or in anonymous form in those exceptional cases where concerns over user security and anonymity are involved.

Maintain the integrity of Tweets and not edit or revise them. Tweets may be abbreviated for display purposes and as necessary due to technical limitations or requirements of any networks, devices, services or media. Get each users consent before sending Tweets or other messages on their behalf. A user authenticating with your application does not constitute consent to send a message.
