What is that word or phrase for when the attempt to stop something ends up backfiring and instead causes that thing to get a lot of free press and therefore becomes much more widely used? I would love to see that happen here. I wasn't familiar with the Language Transfer project before, but will be trying some of their lessons now. EDIT: ah, I was trying to remember the "Streisand Effect"
