Ok @crypto.piotr thnks for your post. Are you using the list on https://steembottracker.com (when you scroll down to Promotion Services? - other bots)

I don't think you can say which type of service is necessarily better. I'd say bots are good for getting SBD, but resteeming is good for Followers. Having said that, once you've resteemed for a while on the same bots, it gets harder to get new followers.

What would make this post v. useful is whether the Resteem is instantaneous, for timing is really important for getting the rewards within 30mins. It's annoying when you send SBD to a resteem service and it deliberately gets left after 30 mins.
I like gangresteem for one, as it's instant.

It would be nice to see Resteem bots /humans focused on particular subjects more, that way people would follow more, and enjoy having them in feeds. ?
