I will definitely make a note about this, but the main reason for your question: Data saving. How many locations at different times do you want to save? Do you save every second for the last 30 seconds? What is a comparable distance? On what events does the check trigger? Even more of a concern: What if your algorithm breaks for a border case and causes a disconnect or ban? How do you deal with the consequences? Even more important than catching cheaters, is to make sure everything flows smoothly. For RO in particular, there is a random-teleport skill/item, which makes your description impossible. As for attack speed hacks... there's a lot of variations. One simple variation is a memory edit with T-Search, since attack speed restrictions are almost always client-side, due to computation tradeoff.
