Cheap tactics are fair game for the most part in my opinion. They're an inherent part of the game, how can it really be cheating? But if someone overuses a cheap tactic then it gets annoying.

But the examples that the thread starter posted definately seem fair enough for me.

And I really don't see how using KOTR in FFVII is cheap, it takes so much smurfing work to get, you should be able to use it when you want.
