I'm with Susan on there being no simple ways of solving problems permanently. Guitars don't stay in tune, but that's no reason not to tune them up every now and again.

The reason I put up the suggestion was that I'd found myself wanting to say something about a particular topic, but realising that if I did so in that thread it would keep it alive when it would be better dropped out of sight.

And then I saw another thread started in a trolling fashion, and perhaps by chance, perhaps intentionally, someone had started a separate thread on the same topic which didn't have that trolling intent and impact. And I thoiught, that's not a bad idea.

I'd be against having anything which sets out to challenge the troll, such as a link to a new thread. On balance I think that would just muddy the water, and any direct challenge is probably seen as a reward, sinc eit is a response.
