Take this post for example:
Every comment (except for the one yesterday) is fake. Look at the similar pattern in their usernames, then look at their post histories. A few posts in large subs to get enough karma, and then nothing but straight shilling. The 300 upvotes are fake too.
Also sort by top posts of the month. Almost all the top posts are for the same ICO.
I get that most of the posts in this sub are just ads, but when you have entire inorganic comment threads in posts with hundreds of fake upvotes it makes it harder to find information.
