why is there that trap link in niche boards that says
"If you click on this link, you will never see this site again."
what if somebody were to accidently click that link?
why not just hide the link or require a password.
to completely ban somebody for a mis click is rather extreme.

This is not the iichan error reporting board. That is here: http://iiichan.net/dis/error/

Furhtermore, that link is hidden. If it is visible, you are using a broken browser, or trying to view an image board in lynx.
