Ask HN: How do you ban websites for yourself?

I use /etc/hosts, the slight friction of having to open the file as root and comment/uncomment acts as a nice bar.

I have reddit, twitter and facebook blocked all the time and HN some of the time.

I've found that over time I use the blocked sites less and less as I break the habit.

I frequently erase the history and bookmarks to a site.

For example instead of being easily able to CTRL+T and type 'ne'+enter to get to HN I am forced to type in the full URL, which gives me pause to think if it's how I should really be spending my time.

For Hacker News, there's |noprocrast| on my profile page.

But generally, engaging work works better than anything else.
