Well, in their case, they were the only users by now who ignored both mywarnings and my flags. But right now steemcleaners and swissclive gave a bit of help, taking them to only 2 reputation. If they will reach 0 reputation, then their posts will be hidden by default and the newcomers willnot see their comments anymore, which I think will happen pretty soon. I am glad to find people who appreciate my efforts, you must know that! It would be horrible to imagine what would happen if there would be 10 spammers like this one.
