Same here 4 so far just over a week ago. Hopefully it will stop. I don't know the whole story or which one is correct. Supposedly someone got mad with @steemcleaners and created the accounts to downvote anyone the is possibly associated with them. All the accounts are Rep of 25 and all cast -100% downvote with just the starting SP. It shouldn't harm us, but it's still the idea of . 'We've cracked down on fraudulent signups and accounts. Then this happens.
