Honestly, I don't think that EULA would actually hold up in court since it is contradictory within itself. They are trying to divest themselves of responsibility for the content available on their platform, whilst at the same time claiming that content as their own. Neither of those things is remotely realistic.

Actually getting them to court however would be a huge feat, I'm sure the have a cadre of lawyers whose sole purpose is to keep them from ever seeing a courthouse.

Twitter can go suck a bag of d's as far as I'm concerned.
