If watch the Free Bitcoin Sites thread you can stay updated on what sites are working
and what ones may be down for various reasons. These sites are verified before being
added to the list and are checked everyday by me and other followers of the thread.
Many of these free BTC site's owners/operators follow the thread as well and will post
themselves when there is something to report about their site.
Beware of copy-cat threads and web pages, who don't take care to check or maintain
their listings and often have dubious sites/links ( sometimes hidden behind url-shortener links...
i.e. you can't be sure what site you are actually going to when you click on their links. )
The link to the Free Bitcoin Sites thread is in my sig.
