Well, i made a bunch of research a few days ago together with logic and hivewatchers and another friend - and found more or less the person behind this spam-attack wave. everything proofed down with screenshots of discussions, registrations etc. And yes, it's related to a Splinterlands Bot-Army and looks like it's someone can't get enough money since he is not anymore able or better say he is only able to monetize the huge amount of Splinterlands Bot Army anymore in Splinterlands and looking for other (unethical) ways to gain profit. idk if i should make my research on this public... if interested in more details - i'm open for discussion on discord.
Edit: As of right now i didnt saw any consequences for this bad action this guy did - either on hive or especially on splinterlands side of things.
He should be named and shamed, both the buyer and seller, but I guess they don't care
Thank you for conducting a thorough investigation and uncovering the mastermind behind the botnet.
