there are no ideal settings and tbh, only an idiot would share his settings on a public forum.
the more users use the same settings, the more likely it becomes for IG to detect the same activity, don't you think?
I believe IGs detection system is well developed, you can clearly see that more and more users are getting banned. If they aren't yet checking the same activity across many accounts, they probably might be doing it in future (if they really care).
try to be as unique as possible, test the waters, if you lose one account, learn from it and adjust. believe it or not, but it's actually problems/new circumstances that help us continuing growing.
