Blocking the crackpot

I disagree. If someone's contributions constitute little more than wasting other people's time and trolling, we should not hesitate to use all means to eject them.

Also, wikis work because of the "someone is wrong on the Internet" phenomenon. But the flip side of that is that there will always be someone "at fault" of feeding trolls and generating endless drama that someone will have to keep in check. Conveniently, that person is not you.

If you want an "open environment" for discussions, go visit 4chan. This is ostensibly a dictionary-building project. Let us keep it focused on that task.

Indeed, if people are going to feed the troll then that is a problem too but a ban to the troll themselves easily stops it all because then the troll cannot leave another reply for those who misassume good intentions, be it due to wishy-washy AGF junk or any reasons, to in turn reply to.
