Siwa's got my number, and when its time to move on, I don't have much of a say in the matter.

I understand this, also 110% and feel very much the same way, though i am not against hedging my bets with Siwa where possible.
Of course i am sure you agree that the problem with videos like these is as Anthony suggests. Newbies see it on the web, they see the materials being handle without too much precaution, and they just assume these things are 100% safe. It's pretty irresponsible really, but there is not much we can do about it beyond stating the warnings here.
