Goes without saying, but... For all clans recruiting, your clans are in increased danger of being flagged due to the increased hacker count (which I personally like to call "Hacktoberfest"). There is no way to tell when a person will glitch (at least hacks are easier to find), but a close eye should be kept on all members of your respective clan that arise even the slightest bit of suspicion (depending on how paranoid you are about it, for the lack of a better word).
With this, I suggest for everyone to be on their guard and watch who is taken into the clan. Be stricter on your recruiting for the time being, and be sure you can ABSOLUTELY trust the recruit before bringing them under your clan name.
Although a reported and banned hacker will just create another account, all we can do is what is shown above and collect evidence to report as many hackers/glitchers as possible.
Also, it would be a good idea to set up designated Elite rooms for your clan, so that way your members do not have to suffer playing with hackers, especially when the other players will not vote/will vote against a teamkick. Elect a member or two of your clan with the Elite Mod to be your official room starter (or however you want it to be done), and keep all playing within those rooms. You could also find other legit clans that are a member of this site and set up a room with them. After all, thats what the site is also about! As legit clans, we all gotta stick together and help each other out in a time like this, as well as enjoying a fun, legit game together.
