not exactly autosurf,its a startup, a site that pays satoshi for you to use their search engine
their original topic is here:
https://bitcointalk.org/index.php?topic=1318008.0don't get too excited,as the current rate is whole 42 satoshi per search and you are only allowed to search 50 times per day 10 times per hour
so the limit is 2100 satoshi per day,for 5 hours of searching
all of the "bitcoin autosurfs" above are scams-they offer ridiculous amounts like 500 satoshi or more per site surfed
and then asking you to pay for "upgrade" to be able to withdraw
