|Can it be clocked?|
Yes it has!
But calm down a bit! It has created some online casino cheat opportunities but they are very few and very far between.
As both live blackjack and live roulette do not use random number generators but rather real human dealers who deal real cards and spin real roulette balls, the games they deal are indeed open to cheating vulnerabilities. But it is not the human factor that is the chief vulnerability.
It is the equipment used by live online blackjack and live online roulette.
In live online roulette, the dealers are spinning real roulette balls on real roulette wheels,so we can make one logical conclusion: If biased wheels can be found in use inside brick and mortar casinos, they can also be found in live online roulette games, therefore if a roulette clocker wants to come in from the cold of outside brick and mortar casinos and ply his craft to the warmer roulette wheels online, he's got tons of live online roulette wheels to clock.
But the problem for him is that, just like in brick and mortar casinos, biased wheels with enough of a bias to make clocking them profitable are very VERY hard to find. I would think that live online casinos are even more wary of this and thus have their live online roulette wheels checked and rechecked and re-rechecked.
So the bottom line is: Finding live online roulette wheels to clock is extremely tough--but they are out there!
