The great thing is that the Hive communities and many Hiver are paying attention and have mutated and downvoted many of these posts.
I in the community where I am a moderator have downvoted at least 20 posts copied from posts published 4 years ago.
Like you I have found the Hivesearcher tool very useful.
According to the information I received, the Hivewatchers team will take further actions against the botnet users to make them nowhere to hide.
