None of us want to believe it but...

1) Unless you're playing higher than 15/30, you have very little concern.
2) Most sites' automated collusion dection can easily identify collusion patterns, so what's shown in these videos is no more effective than 2 friends colluding from remote locations using IM technology. They will be caught and will have their bankrolls seized.
3) Most cheaters are bad players who barely beat the game when cheating. They are easy to identify at the table before you lose too much. (the exception are the very good cheats, but they don't play as low as 15/30.

To sum it up: non-issue.
