Hi, thanks for your comment. I do not know how to identify a bot with 100% accuracy. However, most bots on Steemit will comment on your posts and say something along lines of - I'm a bot created by this user and you received an upvote to show your support please send SBD to this user.

Bots work in a very simple way, they basically go to all the trending/hot posts and will upvote and leave a comment. The problem is most of these bots are owned by a few whales and they will use them to upvote themselves and to get new users to pay their creators for upvotes. So basically is like having a team of employees working for you to generate money from Steemit. Just imagine if just posting by yourself you can make 1 dollar with 10 bots you can make over 10 dollars.

Anyway, you gave me a great idea, I will write a detailed post explaining how these bots work so users can be aware of them and stop upvoting and sending money to their creators.
