Normally we recommend abuse reports come through our abuse form on x10hosting.com; nevertheless, we will investigate this further from here. In the future, due to the way some forum softwares are set up (including XenForo), you may wish to report it to the developers directly, as in XenForo's case it is often difficult to identify if it is nulled/warez or not - XenForo can run it through their license system and notify us directly via their piracy team if it is indeed an illicit install however.
