IDK about first question since I didn't play RSC till now. If they used to ban botters back then, then I am sure they will do so now. Even if they didn't before, Jagex had gotten smarter now. So you can be sure about getting banned if the scripts doesn't have anti ban
As for the second question, Yes they ban your account, and since your account is the same for RSC and RS, you will get banned in both if they ban you for macroing in one.
