Nobody ever used the #familyprotection tag until we created it for the @familyprotection account.
It is used so that we can find posts to vote on and resteem for our followers.
But now so many people are using the tag without understanding the purpose, and it creates a LOT of EXTRA WORK for me and the other moderator to find the posts worthy of our votes and resteems.
