As long as you dont use any mods you wont get affected just by logging in a 3rd party app, iirc the best way to be safe is "if you can autoplay on the real app and achieve the same results, is A-ok"
They check only on the stages you clear, its why auto win is not advised as replaying a stage and immediately winning is impossible, and of course they test it with annihilation, where its steady reward is an obvious cheating sinkhole
So far Yostar games are pretty lax in terms of banning, you just need to make sure you dont stand out, the usual hide your achievements until you are at the believable level
7 day huh, i guess thats a warning shot, mines a 2023 year ban, been using the mod for a year, not the biggest loss, was just trying to get limited units
