It's not different with @bago, there you get for 0,75 SBD a whopping 110 upvotes for practically zero return. I use the service because it pushes the article to the top of the trending page of the chosen categories.
Overall, I believe that has more use than spending your $$ on resteembots that resteem to other bots (as you do it with the resteembot).
I didn't know that the trending page is based on # of upvotes... even if they're worthless? That's something I didn't consider. It doesn't seem like 40 upvotes would make much difference, though. @ironshield
