Yes, for "unethical behavior" for taking a data set I have full rights to, and instead of doing a traditional XenForo import of those members, creating an XML file for each member (in the XF XML import "template") to import members one by one and sending them a password reset so that I know that (1) the email doesn't bounce and (2) how many would engage from the import.
With a traditional import, I could only do an email blast (as you cannot throttle mail at this time). Doing it that way, with so many bounces in that set, could have caused my email services to be suspended. However, doing it one by one with a forced password reset would stagger the emails to not cause such an issue.
However, that was deemed "unethical", and as such, I could no longer be a member of that forum.
