There has been not much change in Hive account@appreciator's Terms of Service but they needed to be stated again clearly to remove any confusion for new users.

Spam Control

• You must not be black-listed by Hive account@cheetah and Hive account@steemcleaners.

• If any report of plagiarism is found on post then we reserve the right to unvote it without refund

• If you are found to be repeatedly abusing rules then your name can be added on Blacklist

You cannot repeatedly get those posts upvoted, consisting of one pic and tagline only because there will be now more rigorous blacklisting

If you want any issues or concerns to discuss with regarding service you can contact me on discord or steem.chat Hive account@bluemist
