Silverstrings

I have no idea, I think it means whatever you want it to mean. Usually folks interpret it as visiting the sub and then going to a different one but you could also interpret it as leaving permanently, like I said it isn't actually enforced. It's just meant to encourage lots of irreverent posting.

Well sort of the point of 196 is that you can post almost anything, the only rule is that you have to post each time before leaving. This rule isn't enforced for obvious reasons, unlike the ban against tankies.
