This version adds a long challenge for disable the blocking for a custom period of time. Fixes an issue where "O" "0" "1" and "l" all look similar, by removing them.

The modification to this version is very small, it just adds some js to prevent copy and paste of the challenge code.

This latest version adds a random challenge for the user before they're allowed to disable the Reddit blocking feature, this is meant to engage the mind so they don't mindlessly click "disable".
