... Report the people you see? It's easy really, while a mod can't see everything, there has got to be at least ONE person on FH that is seeing these people do wrong, and yet no one reports them. Hiring one or two more mods isn't going to stop it, it won't solve the issue. Because one or two more people doesn't mean the mods are going to spot it. But if people would actually be bothered reporting, then they would be gotten rid of. Sorry for the rant, but SERIOUSLY?! The only way to be 100% certain that a mod is seeing what is going on is if EVERYONE is a moderator, because there will ALWAYS be something the mods can't see, and hiring a TON of mods just to make sure they are covering every pixel of FH at every second of every day is ridiculous.
To report, all you have to do is take a screenshot that includes their username and evidence of their wrongdoing. Simple. YET NO ONE DOES IT.
Once again, sorry for the rant, but it is starting to get ridiculous the amount of people who think just going out and grabbing more people for the mod team is the answer to everything. You saw these people doing wrong, and complain they haven't been banned. Guess who has some part to play in that? You do.
