Disemvowelling

From a new Q&A on BoingBoing's comment moderation policy, a technique I've never heard of before: disemvowelling:

Q. All the vowels have disappeared from a paragraph I wrote! What's going on?

A. We did it. Someone (a moderator, one of the Boingers) was expressing displeasure at your remarks. The technique is called disemvowelling. It deprecates but does not delete the remark. With work, the disemvowelled text should still be readable.
