A "Sin Bin" filter for Twitter bores

This morning I picked up my trusty Twitterscope, but to my horror I saw 3 things I am increasingly seeing from people I follow who, though basically good eggs, are sometimes tempted to overshare:

- The conference/conversation/date they are getting to/at/with, via a stream of 140 character updates

- Every so often they are tempted to pimp (or worse still, retweet one of their idols pimping) something fairly vacuous and inane.

- Generally pumping up their own volume

What I want is a temporary filter that "turns them off" for a bit. I don't want to go through the hassle of unfollowing and then having to remember to refollow, I just want them turned off for a few hours or so until they get over it.

In other words, rather than wave the Red Card and send them off the field, this idea is like the concept of "Sin Binning" in sports like Ice Hockey or Rugby, where temporary overenthusiasm is met with being sent off the pitch for a few minutes.

Even better if they could (optionally) know that a whistle had been blown so they could (ahem) reflect on their tweeting behaviour, something like:

@curmudgeon has sin binned you for being boring dahling ..... (and then you can either add the reason or not)

This of course is in addition to my keyword filter which would of course come preloaded to filter any twts with the words "awesome", "kitteh", "om nom", "special" or "lunch" therein.

Now that would be awesome.....
