The blacklist is for users who have been caught in one or more of the following activities:
- Spam (Frequency, Quality)
- Plagiarism
- Fraud or Scam
Every account has been manually researched and verified, all 3200 of them. When a user is considered for our blacklist, we look at the account, not just one particular post. You can find more details in our Terms of Service.
Our blacklist is shared with other bot owners, SteemCleaners, and curators. You can find our full blacklist on Github where it is updated daily. You can grab the raw copy of the blacklist.txt to use it in your services.
If you find users you feel should be on the blacklist, submit a pull request or let us know on Discord where we have an anonymous #abuse channel. You will not get a response back as it is a write only channel so users can submit without fear of reprisal.
If you have questions about the blacklist, you can reach us on Discord.
