It works great if you pretend to be doing something good.. this allows you to leave spammy comments, which you then upvote as late as possible. That way, your poor ability to create content is not as visible. Take for instance this post - it is probably the worst content I have read all week (I never read trending, but stay in my feed). The only reason I came across this was @the-resistance mentioned this in a server so i took a look.

My point is, it is very poorly written, so this user has created a perfect scam. He downvotes others using a big fear tactic - he's controlling spam. Then he leaves a spacer comment (actual spam) and upvotes it later on.

Brilliant way around making money without too much effort, isn't it ;-)
