I had their delegation removed, they already were nothing more than 15 accounts doing a 2 cent downvote combined. Now without the delegation for new accounts, they do nothing at all.

There is not much that can be done, they don't post, they don't comment, they only flag but all 15 accounts have a combined 6-7 Steem Power. Their votes don't even register as they are counted as dust votes. You can see they were placed but they have no impact on the financial rewards of your posts.
