Sure, they fake all sorts. Krugerrands are some of the most popular bullion coins. The fake ones are usually plated with pure gold, which is a very soft malleable material and can be rolled extremely thin. Real krugerrands are alloyed with copper to make them more durable. The copper also gives them a different colour, so fake coins usually stand out like a sore thumb. But you can do basic checks such as measuring and weighing them to verify they are genuine. But a good way to test them is to download a bullion pinger app. Search the android app store for "Bullion Test Free". Basically you can tap the coins, and they'll ring like a bell with a very specific note. Plated coins will ring with a different frequency.

I'm pretty sure PR companies are managing the content on the default subs, probably the upvotes too. There are websites where you can buy reddit upvotes. In 2016 correct the record were spending millions to game reddit and twitter. Reddit admins have never once mentioned astroturfing, which leads me to believe they are in on it.
