Posting Soccer Goals On Vine Is Illegal, Say England's Premier League

New submitter JonnyCalcutta writes: The football Premier League in England is warning about posting clips of goals on online services such as Vine and Twitter. The claim is that posting these clips is "illegal under copyright laws." I'm naturally dubious about blanket statements from rightsholders already known to push the truth, especially concerning such short clips, but I don't know enough about copyright law to understand the implications fully. Is it illegal? What can they actually do about it? Does adding commentary give the uploader any rights to post?

PL = Honorable Institution.

Even if thee free publicity would lead to more people watching and consuming soccer-related products and services in the long run, It's always good to see honorable institutions such as the Premier League inciting everyone to be a good citizen and abide the law, at the cost of them losing money. A true example to follow.
