I was listening to the podcast and just realized how potentially creepy recording the 30 second mp3 could be...
I can't think of a specific example, but I could just imagine you getting a really weird request...
Donate enough to get two.
Request one of Ross moaning.
Request one of Tom moaning.
Once you get them, overlay them, add porno sound track, and publish on the internet.
And that's just from, like, thirty seconds of brainstorming. Probably could get creepier if I put thought into it.
