"Effective" masking of links is relative. To some members of the HN community saying that it is impossible to mask the links is the only empirically correct statement. But my aunt and her pinned collection of knitting crap isn't going to break out an HTTP sniffer to see what is going on behind the scenes, the masking of overt monetization so users continue to labor under the delusion that they aren't being marketed to could be all that is needed to be "effective".
Camouflage doesn't render a soldier invisible but that doesn't mean it's not effective.
It'll only be effective until a well-placed, shrill-toned media story exposes it to everyone. Be upfront about it and you'll be less likely to find yourself on the wrong end of "deception" charges, however trifle and ultimately meaningless the deception is.
