It would be better, but maybe only for me, but probably not possible, if those short threads could be removed. A bot could do that, I guess.
I don't see the short Threads (where the OP disappeared) have an effect on anything apart from the disk space needed to store them - and disk space is so cheap that it would not be cost effective to weed them out.
I'm assuming the discussion of having a "bot" is firmly tongue-in-cheek. If not then I would be against it. I can think of nothing worse than a newbie's post being dumped by some silly robot - no matter how silly the question.
To put things in perspective the Forum's anti-spam software can't even detect posts about search-engine-optimisation.
