I see no reason at all. Can anyone explain it?
I didn't delete it, but I agree with the mod who did 100%. That was noise. It was a joke, frankly not a very funny one, which was posted as an answer. The entire content of your post was this:
I think it would be a good idea to suspend all too high-rated people like Oli, Rinzwind, etc. for a year or two to let other people do something useful ;-)
That is clearly not answering the question, and not providing anything useful to the discussion. What's worse, it was posted on a pretty serious subject where the suspension of a high rep user was being discussed. That isn't something we (mods or users) take lightly so that makes your post even more delete-worthy.
But the main reason it was deleted was for the same reason anything on the site is deleted: it wasn't answering the question. If you felt it was so important, you should have left a comment.
