I have about 10 legit accounts where I frequently cross-post the same links. I wish there was more guidance on what constitutes substantially similar content. Same URL? Image? Keywords? Hashtags? I accept the fact that I will now need to rewrite every single tweet but it would be helpful to know how NOT to run into trouble with these very vague new rules.
Honestly a better solution would have been to verify accounts like Facebook did and ask us to place code into our websites. This new change makes using the platform for journalism sites very challenging and frankly puts all the burden on the user with no heavy lift by Twitter.
