"Venezuelans farming gold"
There are over 60 clans on Old School RuneScape that speak only Spanish and most of them have hundreds of members. Unlike the RuneScape 3 Spanish Community, the Old School RuneScape Spanish Community is pretty united. Many people are double clanners and many of the leaders know each other. The majority are not Venezuelans and don't engage in any sort of real world trading, but many of them do participate in different forms of PVP whether it's Clan Wars, Wilderness PKing or both. It's hard to say who coined the term "gold farming Venezuelans." My impression at first was that there were a lot of racist gold farmers who wanted to create an enemy to kill to take out the competition. All the English speakers teaming up against all of the Spanish speakers sounds like a plausible explanation. If it wasn't racist pkers that started it, the latin clans spamming "Venezuela" for shit giggles just made the rest of the PVP clans start referring to them as "vennies". I honestly blame those purple wearing Zarosians, but Zamorakians like myself would say such things just to create chaos.
"You have to pay some clan money so they don't kill you"
People paying for protection is the largest scam in RuneScape history. I honestly can't believe some people fall for it. It should be common sense there is no protection on the Wilderness.
"What could be done to remove revenants?"
If it's not broken, don't fix it. I like revenants. It's a good feeding ground. On an average pk trip, you can make 1m+ gp just killing some noobs. Why take away the best money making method for PVP? That's like saying cox and tob should be removed because it's creating too much money for PVMers.
