Yeah, I was being heavily sarcastic, I know for a fact they do all of those things, haha.
The one thing I forget is is they do an approved "whitelist," which, like you've said, I've heard about a bunch, and/or if they have a "blacklist" of supplements that have tested positive (The whitelist sounds more usable, but the blacklist sounds more probable, cuz I supposed a tested and clear supplement provider can always become a fuckup, whereas if some provider is already a fuckup, that can be easily proven, then just stay clear).
Granted, of course a reasonable person can still fall folly of supplements and test positively unintentionally, but that does, like i said, stray outside the realm of ignorance and instead take a good degree of negligence.
Being an accidental cheater only gets you so many shrugs, and still gets you suspended. Or at least it used to. Depends how big a star you are.
