SteemIt may have received a copyright complaint against you for that or a previous post. If you copied any articles or images without permission; then SteemIt has to remove rewards from your account.

There might be a set amount that they have to remove from your account. I would contact Hive account@steemcleaners to get the details of the complaint and payoff the amount that they are required to collect from you.

If you did not violate any copyrights, I would contact Hive account@steemcleaners to find out what triggered the action. It could be that someone is abusing their copyright reporting system.
