I was wondering... I currently have two level 70 characters on my account. Both of which were botted to 70.
I want to make an Evie...however, I wanted to know if Nexon tends to get more suspicious of an account in which someone continues to bot characters to 70?

I really don't want to get banned for making another character...I'm currently equipping and strengthening my two level 70 characters.

They shouldn't. Many legitimate players have multiple lvl 70s. Doing the botting increases your chance of getting caught actually botting, but the raising to lvl 70 should not be a problem. It is Nexon, though.
