Well thanks for trying at least! It is odd as the account is at -0.68. So it can only post about once every 15 mins. Hitting every say, 4th comment with a downvote of a negligible weight - I just tried -1% (but I've got some loaned SP) - would slowly push the rep down further as he isn't getting any upvotes - which makes sense since his comments are invisible. At the very least you've stopped him thrashing the bandwidth at anything near the rate of a few weeks ago.
As to why it continues - some of these bots have a real attitude problem :) Must be all that high end machine learning invested in them.....
I believe it is possible to transfer voting power between users? So you could try a limited run using loaned flag ability - just don't hit any high SP whale spammers :)
Yeah, it's looking more and more like down votes will need to be part of my strategy, I'm just trying to decide exactly how to make it work.
Ok - my background is mainly in networks and what was once called "systems analysis" - badly_drawn on the steem chat platforms (don't have discord) - I have a few ideas - so let me know if you want to chat some time.
Just reached out on steem.chat!
Buzz me on chat if you like - should be around for next 2 hours or so.....
