The Fappening - Now a community!

PeerBlock lets you control who your computer "talks to" on the Internet. By selecting appropriate lists of "known bad" computers, you can block communication with advertising or spyware oriented servers, computers monitoring your p2p activities, computers which have been "hacked", even entire countries! They can't get in to your computer, and your computer won't try to send them anything either.
And best of all, it's free!

IBlockList is the primary host of the list-files used by PeerBlock. In addition to serving up over 10 TERAbytes of data for us each month, they fund maintenance of many of the lists you use every day.
Unfortunately, due to the increasingly heavy traffic they have been sustaining for us, they will be forced to start limiting list downloads for all users, effective Tuesday September 24th. After this date, free users will only be able to download updated lists once per week. If you sign up for their IBlockList Subscription program however, you will be able to update much more frequently - up to hourly for lists which are updated that frequently. If you are getting "Update limit exceeded" or "Error Contacting URL: 400" errors when PeerBlock attempts to update lists, this is why.
