BEWARE OF COMMERCIAL AFDBS: Since you should trust no one, always construct your AFDB yourself to avoid the risk of subversion and mental enslavement. Sometimes, AFDBs will be sold on places like eBay. Do not purchase these pre-made AFDBs, even if the seller seems trustworthy. They may contain backdoors, pinholes, integrated psychotronic circuitry or other methods that actually promote mind control.
