Sorry that is happening. It looks like some troll/bot accounts. They have little HP and none appear to have staked PHOTO but they are a big nuisance on the Hive platform to be sure.
I've muted all the accounts that have downvoted you so far on hive.photo. That won't stop the downvotes from appearing but it should prevent the accounts from depriving you of any PHOTO token rewards should the accounts ever stake any PHOTO.
