The word 'uncovered' does not mean that they studied it, only that they discovered it. Indiana jones frequently uncovers lost treasures and civilasations but he doesn't study them. Naturally Malak and Revan found Malachor and the teachings there, thus 'uncovering' them.
Revan and Malak were practitioners of the Force. They were not simple explorers. Bane specially pointed out that Revan had great knowledge of Sith Lore and knew many extremely deadly techniques.
Both Bandon and Malak demonstrated variants of Force Drain. Revan defeated them, right?
My disciple, concentrate on the Jew. While he and SWL share certain critical similarities, there is at least one critical difference: the Jew is capable of higher level reasoning. He and he alone of your enemies is worthy of your wrath.

The point is that the Jew is a religious and political conservative and is therefore the Exile to your Nihilus {or vice versa}. It is your destiny to oppose him.

I would have killed the galaxy for you. You're like staring into the heart of the Force. And so forth.

I'm not sure you win either way (but since you're the king of delusional, I'll let this go). It's a theory based on deductive reasoning. If both Kreia and Nihilus can harness the specific power they stumbled upon on Malachor V, how much moreso can Revan, who studied the underground sith cities and god knows how much information was down there. Furthermore, Revan has shown a knack for trying to learn counter abilities to something that wtfpwned him the first time around (Vitiate's mind ****), so it stands to reason that there's a REALLY good chance Revan knows a counter to the Nihilus drain, while learning in the underground cities on Malachor V. Finally, I don't think Nihilus was able to drain just anybody. I always said if you were a wound in the force or found a technique to simulate that effect, you could defeat him. But I win, so I digress.
Isn't this easily solved when we look at how Revan trained a group of Sith assassins to hunt down Jedi and do it using the drain technique? The more powerful their targets, the more powerful the assassins became. Then Kreia and co took them over after Revan vanished. Kreia then took the drain to it's next logical step, and one way or another, opened the door to turn Nihilus into a planet eating monstrosity.
Did he? I thought it was soley the Triumvirate that experimented in this technique. you might be getting confused with the assassination squad Atton was in.
I don't believe Gamebanshee or 'the Shadow Academy' are allowed to dictate canon. Only the first link has a medicum of believability as it claims the information comes from the TSL website. Unfortunately said website no longer exists.
In any case there is no mention of the technique. Nor, even if Revan did establish the Sith Assassins, does that prove that he was skilled in the technique and able to use it. Nor, even if he was knowledgable about it, does this indicate that he can defend himself against it.
