I have had my rights infringed. I only found out by sheer chance. It has happened to me more than once.
Ask around others in the business - and you can get similar stories.
If you are lucky enough to find out - and if you have the proof, and you approach the company concerned - they simply pay up what they should have paid in the first place.
Often it involves using your work in a foreign country. It is extremely unlikely you would find out - only if you happened to have a friend who was in that country at the time - that friend just happened to see your work - then reported back to you. Preferably your friend should get some kind of proof as well - but they would only do that if they understood the business - otherwise it would not cross their minds to do so.
If you don't find out - you never get paid.
These are not tiny sums - typically £1000-£5000.
I am convinced I have been ripped off tens of thousands this way.
Companies have nothing to lose by doing it - in the unlikely event you find out - they pay up. Otherwise they don't. It is that simple.
I am not talking about spotty teenagers in their bedroooms downloading a few songs.
These are companies ( corporations in American).
I have never heard of this guy - but his podcast is interesting - about 4m10s in : http://www.youtube.com/watch?v=znm-d...eature=related
