Idk. I think it depends how much you use it. I've been using this hack for a couple months now. I never used freestore because I heard of banning.
But I'm still using instant heal, instant upgrade, max xp, unlimited egg fragments, and no comment required for building and still haven't been banned. But I also use them VERY sparingly. Like 1-2 times a day. Except instant heal. That's always on and no ban.
They are catching on only because someone sent them the link to this page. So soon enough this entire hack will be good for nothing. And the creator wasted their time
