The $0/hour is to redirect your most popular slack sites in (e.g. Facebook) using /etc/hosts. You can redirect them to localhost, or to something you personally find annoying. :P
Just make it so, that's it's trivial to get around. (Like the /etc/hosts thing.) Then you instead of spending time thinking of how to get around, you will have to admit what you are doing.
This is incredibly true for me. I blocked time sink websites (like HN ironically) in /etc/hosts for about a day, and then I constantly went back and reverted my changes. Then, I wrote a daemon that constantly checks the host file and puts the blocks back if I changed it. I tried making the installation and operation as obscure as possible and try to forget the metaphoric key. However, I eventually ended up spending a bunch of time to rediscover what I did, so I ended up disabling this script as well...
It worked for me. My reddit habits turned into mouse scrolling looking at pictures, it was "fun" and required no effort on my part.
The first week I keept trying to access it and finding my 'default' vhost. Now I don't even miss it when I'm on my PC. I have Alien Blue on my iPad but there I can't just scroll and scroll, I read content I care about on the reddits I like and not /r/all!
