Hi mate.
morality may be seen as a strong word by some but yep that's part of it. The other thing is that ovo dj's spend a lot of money and time in building collections and discovering new records. For many it's their livelihood.
Imagine that you'd travelled to the states, unearthed an unknown record, bought it back and the record became massive. Then three months down the line someone somehow counterfeited it and started playing it. Wouldn't you be angry?
Loads of other reasons too. Well be here all night mate!
Anyway welcome to the site.
Pete
