I'll humour you even though it's a waste of time :)

That's quite a mouthful of fluff, but you don't present a single piece of evidence. Ats-david is a valuable curator and to downvote accounts delegating voting power to his guild (trail) for no good reason presented would qualify as abusive behaviour. These are just users who believe in ats-david's curation and want to contribute to it. Perhaps you should investigate adding @blacklist to the blacklist. :)
