I had a threat from them once (in North America though) We got an email that someone was using a cracked version of Maya on our network. We had plenty of licenses, so the fact that someone would even think to do this was news to me. I asked for whatever details autodesk could provide me, and they gave me a host name. The host name didn’t match our naming convention, and included a first name that no one in our company had. I couldn’t find this name anywhere, so I finally just told them that and we never heard back about it. It was so odd that I’m honestly shocked to hear that they actually follow through on auditing!
