I've been using randowhale and seeing how much value gets added each time, and it appears it's very slightly +EV for someone to use, but as you said it hurts the rest of the pool not using it.

I was going to write a similar post but stopped myself because I thought maybe there was a chance randowhale was destroying the steem sent to him (is that even a thing still?), which would be cool, and I didn't want to post without researching it first. I assume that isn't the case though, which means randowhale or whoever backs him is just making bank for making a simple bot. Definitely need to stop it
