As of now (November 4, 2017) I have used a lot of up vote bots. After not being on the site for ten months I decided to get the site a try again and someone told me I could use up-vote bots to get my reputation score out of the negative thats why I'm writing this post. Most of the up-vote bots are biding bots, so far they have not been any good. So far the best is randowhale. Randowhale is not a biding bot its more of a pay as you go, once you pay you get the up vote right away. Thats what I like about it, I have used bellyrub & steemthat with out getting a up vote or a refund. So beware of those. Another good thing about randowhale is you can use your steem to buy a up vote instead of just SBD like the bid bots and minnowbooster. Minnowbooster is also a pay as you go voting bot but they keep changing there rules for how much you can spend and when you can spend it.
I hope this has been a help to some of you.
So thats it for today thank you very much for reading the post we will be chatting again soon.
