Sorry to break this to you, but the people writing bots can also get over this barrier very easily - see that link to the faceswap in this thread? That makes it possible for every person with a bit of tech understanding or at least a bit of persistence to ignore this. it’s not even a speed bump for people whose job (yes, job) it is to write bots.

This does nothing to make the bots go away, but it gives Meta a full facescan, which is the fucking last thing to hand over to anyone - a data breach at Meta would mean that everyone around you will get scammed by videocallers with your face; not even your bank manager would be able to detect that something is off if he knows you personally (a short phone call with you to get a voice snippet makes the illusion perfect!)

The political shenanigans in the US are also a reason to NOT give facescans out to anyone.

The solution to bots does not lie in giving up your anonymity. There are no shortcuts here that don’t do more harm than good.
