From TFA: "Some users are unable to view WikiLeaks material unless they choose to donate money to the site."

Randomly dialing numbers to find modems is sufficiently similar to randomly dialing numbers to find idiots to at least consider he might be making an analogy.

But why only those two?

There is no such thing as asking nicely to speak to someone who speaks English when the person you are speaking to does speak English. Regardless of how well you feel they speak it, this is always rude.

Honestly they probably only want to track it so they can separate it out from other activities. For example, if a person takes a whole hour of personal breaks one day there is a good chance they'll ask that person why, at which point the person would have to explain they had some bad burritos for lunch. Alternately if they can see that the majority of that time was spent on multiple bathroom trips starting after lunch, they know they probably don't want to know any more than that and no body has to waste anyone's time asking questions with embarrassing answers. As long as they aren't giving you or anyone else (that isn't clearly abusing the button) a hard time about the amount of time spent in that mode, and as long as they aren't posting the information where everyone can see, It's probably something you should just ignore.
