So, someone is asking me to help them out by adding some themes, addons, etc. of their xenforo site that they just asked me a few hours ago if I would help them with installing mybb, and somehow instantly changed to needing help with installing stuff for Xf. How do you tell if someone is using a Nulled version of Xf? I don't want to help someone out if they're using something illegal as it could damage my reputation, and it seems really sketchy how they asked me if I knew how to use MyBB one second, and then the next is installing themes in Xf. If someone could let me know how people find out how to tell if something is nulled or not that'd be great.
