I believe so, yes. This has been discussed and proposed in California, where the so-called Blade Runner law would force all automated accounts to self-identify as being automated. I think in this case, transparency is the solution. There are all sorts of potential positive uses of bots and automated tools in the social ecosystem, but as consumers, we should know whether we are being targeted by one, because, importantly, this will become a much bigger issue as we engage more and more with agents and artificial intelligence-driven entities in the digital space.
