The appreciator should have appreciated your persistency :D , and postpromoter should not have ignored your wonderful offer :P
Nice, funny post, lol
Now serious: I have stopped using these bots; I may use them occasionally, however. I found that the ebst time to use a bot is when the price of Steem is rising. That is when you would profit most from the bot; Also, only a handful of bots are good, especially, the one you mentioned.
