You do know that Vespa searches through mod forums right? You are asking in a known public modding forum "how can I not be banned when using mods" as if they can't implement new ways to counter what you guys seem to think is "Safe"
just avoid for joining a big guild (big is a guild with a high level players on it). Sometimes they check your profile, especially a noobs, and guess what, there is a log of your latest map (i mean how further you clear the story), some whales might report you if they think it is abnormal.
Hell...
in this game, never use (turn off mod) when you're going to clear the story mode. Turn it on when you already clear it, i mean for normal and hard game mode. Do hell mode when you already have a good team.
Never use it on raid. You can use it on tower, but make sure if you're not advancing it...
