Zkq has sent me video proof of the screenshots he posted in which there's proof that he was infact working with EC to get information about the aimlock. I've also recently found out he has worked with EC in the past too (in summer 2017, before aimlock) to uncover other types of hacks and to get them information about it. Therefore I don't really believe that he has used aimlock for "personal consumption" at all, but instead to gather information that he could pass on to EC scripters, therefore, there will be no bans.
Nonetheless, I appreciate the help of everyone who provided information for this case.
