Doubt you're gonna see this, but I personally know the guy who "impersonated" you on Reddit. Long story short it was just a joke that got blown way out of proportion and he has no ill intention towards you. I told him that you have both a reputation and a job as a youtuber to maintain, and that you've already dealt with actual impersonators in the past. Basically just told him to be more careful.
Just wanted to let you know personally that he wasn't a "real" impersonator, and that he has nothing against you. Hopefully this clears some stuff up for you.
- Much love for your work, MechZilla. ✌
