First, hacking is a Federal offense which results in real fines and real prison time. I’d suggest you let your parents know he made the threat (if you’re a minor) so they can notify your local authorities and your ISP of the issue. His gamer tag and user name should also be reported through proper channels to Microsoft and 343. If you’re an adult, 18 or older, or otherwise emancipated and considered an adult in your jurisdiction, you should do the same. Hackers can be caught through digital forensic analysis and I firmly believe they should be caught, tried, and sent to prison for a very long time.
Next, clans aren’t defined by member count just like deserts aren’t defined by temperature. the world’s largest desert is Antarctica. (Deserts are defined by amount of LIQUID precipitation fall in a year, melt the snow fall in Antarctica to liquid form, it’s a desert.)
Clans are generally characterized by competitive play as opposed to casual play or playing for fun. Clans are formed in order to play to win. Clans typically require a minimum KD ratio, minimum positive spread, and a minimum number of hours you have to spend in game each week with the clan practicing.
Clans also typically require knowing call outs, weapon spawns (where applicable), and any other relevant map info from memory.
In addition, clans usually require changing gamer tags to adding a clan prefix to the gamer tag, changing a person’s call out, armor, colors, and emblem. Some clans forbid belonging to any other clan.
Next, some clans require trying out / auditioning, and then going through a familiarization period.
THOSE things are what typically define a clan. If you do those things, you’re a clan whether you have ten or one hundred members.
