Ultimately though, I think this is a fight totally worth fighting because in the bigger picture, it's really our own humanity at stake here. Look at all the bots that took over Twitter and FB. It's a downward spiral.
And soon all the jobs that people got meaning from, but complained about having to do :)
It also makes it more difficult to work out who you can trust in terms of new accounts because scammers are gonna scam and I'm sure they are going to jump at this opportunity
But at some point, the technology for a half decent web of trust will help in this too, if only to identify scammers in the system. It is required globally already.
