Spam is actually advertising the site, and then saying that you will get money out of it. I gave my opinion on a website that quite a few people are using. Some people may be interested in my opinion. Do I have to talk about Steem all the time, or do I have to say that another website IS a Ponzi scheme? I would call my post spam if I say go to the site without research, and use my code. I actually stated something that @craig-grant stated on one of his videos. But since I wrote something about it vs. putting it on a video, it could be considered spam?
