Did you report that content to the person who created it? It's between them and whoever it is that is spreading the oar in question. It is up to the original content creator to file a DMCA and report the alleged infringement.
If you're not the original creator, it's not your fight. Point it out to the author and go your own way.
I see two problems here. One is that you're spreading FUD that damages opensim far more by painting all oar makers as thieves. That's offensive, and it would be better *for opensim* if you were more careful and more accurate in your allegations.
Most oar makers use their own creations, or some -like me- take care to use established open source content sources such as opensim creations and lindakellie.com.
I feel your depiction is insulting and irresponsible. You, madam, are spreading FUD and it's not appreciated.
The other problem I see is this: "enterprise users" expect free content but want to dump all of the responsibility off on the people they get the content from. My attitude is that if you are an enterprise user who is primarily concerned about liability, you should rule out using free content unless you're willing to negotiate a contract with individual creators which gives them compensation in exchange for giving your organization written permission.
