Considering you seem to dislike the whole concept of Bots, isn’t the Bot toggle in the Lemmy profile exactly what you want?
It auto ignores all posts and comments made by accounts marked as Bots. Sure, the owner of the account has to correctly mark it, but I feel that can easily be solved by reporting unmarked bots.
But I’m interested, if you would like to expand on it, how would you make a bot opt-in?
The only way I could think of is through PMs, but that would be cumbersome, and generally unfit for purpose, for all the involved parties.
I’m not sure this is going to directly affect that, because their deal talks mainly about financing for the Control game, and the other news is about movie adaptations, so probably it is going to be another team, lead by the newly re-hired Hector Sanchez, working on that…
But who knows, this kind of things are always hard to follow from the outside
