Rather than someone who sees little to no future success with Splinterlands, I think its more of a bot operator that cannot extract profit anymore in wild due to the wild pass and the 2x SPS stake so he tries to go to hive instead to try to extract value since if the person that owns all of those account is the same guy on discord, the guy was very much active in discord and was still playing the game those his battles were also very suspicious. Regardless, this actions are very disgusting and goes back with the massive bot farming that spl has let to operate for a long time.
Thanks for sharing your research.
