You know, software developers know EXACTLY why facebook is recommending dead friends. Yes, almost all of us KNOW that the algorithm has absolutely no way of knowing that dude is dead. We also understand exactly why the trigger "he is not posting much" works.

But for whatever reason, when someone mentions something like this, we pretend we don't know the algorithms behind it. Dudes, you know it's no facebook conspiracy - they are just using some standard algorithms you understand pretty well, so let's not pretend like it's some special thing.

If their algorithms somehow parsed the RIP on his wall and stopped suggesting him, then THAT would be special.
