Steem has a bot problem

1. I did not post anything for 5 month.
2. I have 98 followers.
3. I posted one article related to cryptocurrency.
4. 5 minutes pass.
5. I have 204 followers. All new followers are bots named like "a-0-0", "a-0-1".

Not that I mind having many followers, but I do care more about sharing ideas with other humans...
