I've thought about it, and I do have another account I could use, but:
1) constantly switching between main account and youtube account would be a pain in the ass
2) it would definitely still lead to situations where I try to do things from the wrong account, wasting time.
3) even if I moved my comment habits to a different account, I can't exactly move my comment history too, so I'd still need to do a purge.
