Equally "paying attention" can be dime a dozen. Particularly if people are simply clicking for pay. It would be interesting to see if Synereo has the issue of people creating bots to automate forwarding, liking and comments.
My main point however is that the challenges of Synereo are completely unknown at this point.
They will have different challenges but they do have protection against bots through thier reputation score reo. As in understand if their bots all keep voting for the same person it won't help the rep and it will have the effect of trading amps between you army of bots. You could do it but you wouldn't get anywhere. Basically unless your robot had a good reputation outside your circle it it wouldn't help you. If it did have a good rep, it would. So good bots like cheetah might help but voting bots would have to vote throughout the network to earn you incremental amp.
You do click for pay but you also tune your feed to what you want. In the end time is what is valuable, if users want to read spam for money they can but they can do that now too. I don't mind paying for crypto news but I don't want cooking, car ads etc. I think their formula could work. We'll see.
