Unfortunately, it's extremely easy to get banned. I've messed around with a ton of accounts now, and one day you could use the mod and be perfectly fine, then another you'll just get the ban hammer. The further in you are, the less likely you'll be banned for smaller things like odd power descreptency.
The only advice I can give is exclusively using "Dumb Enemies" in Intercept. Unless you're at Special Intercept, as I had an account reach there and using dumb enemies got me a ban the next day. That specific account was only using "Dumb Enemies" in Intercept, so I surmise they look at factors heavily for Special.
I highly recommend not using the mods if you really like the game, or having an alternative account to use them on. Atk and Def mods only work with Modernia, who no longer has a rate-up and might be difficult to get unless you reroll for her, which I would recommend Scarlet and/or Harran over her. God mode usually gets you banned in my experience, Unlimited Ammo is only sometimes safe, and Dumb Enemies will also get you banned outside of normal intercept.
Mods will only make you progress a little bit faster, and will still take you weeks to get to the end content. All of that time will be wasted if you receive a ban.
Whatever you, or anyone decides to do; Good Luck
