OP didn't specify whom was doing the suing Get out of here with your high and mighty "shut everyone down" mentality OP's intention was most likely to post an interesting article they found
pokefarmer is not being sued, Bossland is being sued, and its been ongoing for several years now. Blizzard has been trying to shut down Honorbuddy for a long time, all of the other bots evolved around it, and now Bossland has a larger offering to more of Blizzards games which pisses them off further. Niantic in all likelihood does not have the financial clout of Activation to pursue legal discourse with Bossland.
Niantic/Nintendo/PokemonCo certainly have enough money to come after anyone they want. They made so much bank last year on Pokemon, they are set for a while. Will they? Probably not, would be cheaper for them to figure out how to make the game better so bots aren't needed or don't work.
https://www.thebuddyforum.com/threa...never-ending-story.280364/page-5#post-2392653 They are always trying to sue Bossland and never do too well. Al their really doing is trying to alter the result that Atari got early on in their legal wars with Nintendo back in the 80's.
Actually, OP specified "pokefarmer" so which entity would possibly be doing the suing was abundantly clear, because I can't imagine Blizzard would have any interest in suing pokefarmer. Reading is handy.
To officially answer this question, as per the OP link, no, Pokefarmer is not being sued. Blizzard is however continuing its redundant crap against honorbuddy, this is however old news because as they sue for that, then Bossland can counter sue for something else. Its the "never ending battle".
