What do you mean by that? If you are using set bonuses for push, you'll eventually get banned. If you use scrolls/weapons to surpass your wall of efficiency, which is basically 'current MS = last MS + stats gained from last prestige', you will be banned. The variable is simple: if current MS is ok, do nothing; if not, ban. That's why anything that boosts your strength will eventually get you teapoted, as the strength gain curve decreases as you advance your MS.
The absolute only way not to get banned is not crossing your wall. And even doing that, if someone spots you and find your data not ok-ish and report, you'll be banned anyway.
If you get banned its a 100% your fault. Ever wondered why there is a coins no decrease option instead of just coins increase? Also nik, all item sets can wait since x1.5 better equip drops is the only thing worth using there and it is not even that good
