Let's take this particular bot as a case study. It's taken your post, and hundreds of others just like it, and resteemed them into it's feed. Now lets break down what effect that has.
Effect no.1 - The bot's feed is flooded
Effect no.2 - Anyone who has voluntarily followed the bot will have their feed flooded with posts
Here's what doesn't happen:
It doesn't flood any tags that this post or any of the other posts appear in. So Except for people that actually follow the bot this bot is of little to no consequence.
You are right. :) - Thank you for clearing it out!
