   your link in memo ! Booster007 Attached !

I think there are more running bots who work to promote posts. But thats all what I found in my research. I mentioned 18 bots that works. I hope it will be helpful for you.

Tips :

• When sending url to bots send just the url in memo. If you add anything else bots will not work.
• Always check the bots profile before you send request.
• Always recheck the amount you are sending because many bots dont refund.

Why to use Bots???

Bots are used specially to keep your post in the top of trending or hot list. And make it visible to more peoples.

Dont forget to UPVOTE. And resteem it to help others to know.
