According to ZPi wire taps (a.k.a. the referral log), someone is selling an "AFDB kit" on eBay. Although the seller links to my site for added veracity, I have nothing to do with this item. The seller is vague about what's in the kit, but presumably aluminum foil is included since they suggest buying multiple kits for people with swollen heads.
Do not, I repeat, do not buy aluminum foil off of eBay that's claimed to be for use in anti-psychotronic shielding. It would be too easy for mind control agents to embed psychotronic circuitry in the foil which would compromise its effectiveness.
The only safe foil is the stuff being sold for kitchen use, since any embedded circuitry would cause noticeable and characteristic burn patterns on food cooked with it. As long as the forces of mind control don't know to what use the foil will be put, they won't risk adding the circuitry lest it conclusively expose their conspiracy to the wider orthonoid population, making the effort counter-productive.
Even if they were able to undetectably embed circuitry in the foil sold at supermarkets, any desired effect would be difficult to achieve due to the multiple layers used in proper AFDB construction, as well as the unpredictable foil-offset from the beginning of the roll, which would cause the circuits to be misaligned and produce erratic results that may work against the psycho-antagonist's agenda -- yet would still be bad for the wearer.
Precut foil sheets sold in "AFDB kits", however, can be produced such that all circuits align properly for predictable effect, especially if the included construction diagrams are followed. Given that the buyer will be a known paranoid or recovering orthonoid, this would make a tempting method for mind control agents seeking the mental capture of anti-psychotronic agitators.
UPDATE: eBay yanked the AFDB kit, so don't bother clicking the link.
