Thank you @cflclosers, I am trying my best to get the hang of this place... it seems like every 10 minutes I learn something new! I actually use them for visibility. I try to gage them using SteemBotTracker, which is a great tool. Most of them will be operating at a loss, but some bot owners are noticing that, and putting maximum loss ROI limits on the bots (you can see them on Steembottracker) Like @postpromoter has a max -10% ROI, which is not too bad. I personally like the flat rate bots better, im new and I dont have much to spend. Some people send like 50-100 SBD to some of the bid bots and it spoils the bidding round for the rest of the group. echowhale is a good non bid bot that ive been trying too lately.
