from the KVR rules page:
Rules:
You may not sell/trade anything that you are not legally entitled to, whether due to license restrictions, not owning the original in the case of software (cracks, warez, etc.), or any other bizarre reason that would make it illegal to sell the item.
If selling software you must obtain permission to transfer the license from the developer before advertising it for sale, failure to do so will almost definitely be in breach of the license agreement. Sample CDs and sample based instruments have notoriously restrictive license agreements so check before you try to sell.
NOTE: You may not agree with the license agreement, and you may plead that it is illegal/immoral/invalid in your country, but that's not for us to decide, if a license agreement states that you can't resell/transfer it then you can't sell it here.
KVR takes no responsibility and can not be held liable for any sales / purchases made through this forum, you acknowledge that you do so at your own risk. However if you have any problems with a sale / purchase please let us know which member caused problems and we will take necessary action to ensure they are warned and / or banned (depending on the situation, obviously).
