IGS Blacklisting

If you were wondering how to blacklist somebody on IGS, this is how: (and yes, it deserves a post since I find it a bit contrived, and discovered it by accident, not when I searched for it).

First click on Member search.

Once you're on the member's page, click on Register in refusals.

The Refuse option (in the first image) show's all the people in your blacklist.

I don't like players who run away by disconnecting from the server when they're loosing, so I add them to this list to avoid playing with them again.

A similar method applies if you wish to add to your favorites list, or request friendship.

Walkover

A few times I won games on IGS without playing a single stone. My opponent probably accepted the challenge by accident and then didn't show up. Not only do I find this unfair, but it bothers me that my rank increases for reasons that have nothing to do with merit.
Why would anybody do this on purpose, and so deserves punishment?
Additionally, the game doesn't appear in my list of games, even though it added to my rank. Isn't this inconsistent?

Fortunately when this happens, one must only wait a minute until the server declares a win by timeout.

Awkward IGS Ranking?

Here is the IGS ranking table, I find it a bit awkward that 15k is stronger than 16k+, which is stronger than 16k that is, in strength order: 15k 16k+ 16k. Anyway, uh... never mind, if it were 15k 16k- 16k I'd find it awkward too.
