Just spotted in my NIS log:
2018-01-12 14:43:52.616 INFO failed to synchronize with Node [Hi, I am Alice4 <NDNQWXFKVVLA6RVUIGLG6AZVF3FRBV7L5WMIZ3ZT>] @ [209.126.98.204]: org.nem.core.connect.FatalPeerException: remote node is evil: REMOTE_LIED_ABOUT_CHAIN_SCORE (org.nem.nis.BlockChain a)
Anything to be concerned about?
