Banning can be done repeatedly and usually shuts down have-a-go-trolls who are too newbie to know how to use proxies. With their IP banned it keeps them gone. Banning proxies repeatedly forces a switch of proxy, so again it is a legitimate strategy. Added to that, Wikia has in-built programmes that disable most proxy editing attempts.

Banning eventually made /tg/ give up on trolling. So I think you're wrong there, Necrus. However, for the rest of the community, ignoring is the best option. Blogs like this just feed them.
