I want explain about it clearly-
You can make money on Reddit but it is tough.
You can establish yourself on Reddit by being active in the subreddits you would like to monetise.
However, this takes a while,you would have to post consistently and provide a lot of value. Once you have attained a high karma count,you may be able to insert links in your post and not get it deleted. This is because you will have built up trust within the subreddit and people will be more trusting and see may check out your offers.
The other way is to create lots of accounts and start posting links straight away. Your post will get deleted but not before some have seen your links. If it's a big subreddits you may get lots of traffic before your post is deleted. This is why you should use multiple accounts and make sure you use proxies. Otherwise if they detect that one IP address is creating so many spam accounts, your IP address will be blocked.
