The web contains many posts that theorize spam harvesting bots won't interpret javascript, and so will miss javascript-encrypted email address. Javascript encryption is not a complete defense The theory seems to be that spam harvesters are outwitted by the need to view source code. They certainly benefit from its existence.ĭecryption is exposed within the page it's intended to protect ![]() Actually, given the weakness of the encryption process, I wouldn't be suprised if that site is hosted or sponsered by spam harvesters. ![]() In the case of the "UnCryptMailto" script, the decryption algorithm is publicly available at where every spam harvester is free to grab it as well. comĭo you see it?
