We typically ask for a non-exclusive license from our contributors, allowing us to publish the work for a limited term. The reason we'll ask you to remove it is because you're probably in breach of the author's copyright - and sometimes in breach of a copyright licensed to a billion dollar megacorp with a big, nasty legal team. If you refuse to remove offending material, we'll write to your system administrator who may disable your account with immediate effect. They are likely to do this because they have as little interest in getting involved in legal action as we do. Their example is worth noting.
Test cases are notoriously expensive to fight.
If we find we are unable to force the removal of copyright material we'll contact the copyright owner, at which point the case is no longer our responsibility unless The Richmond Review actually owns the copyright. In either case you can assume that someone, somewhere, will be talking to a lawyer. Stealing stuff from us, or any other site on the Web, is stupid and unnecessary. It duplicates resources in an unwelcome way and potentially endangers both our own publishing programme and others like it - authors, agents and publishers still have only a fragile trust in the honesty of Internet users. You can help us build their confidence by treating their copyrights with the respect they deserve.
