There is no limit. spam away as your heart desires, but expect downvotes. Are you actually trying to stand behind what you've done? You are clearly trying to extract value. I'm not sure what made you change from the content that you started off with, but if this is what you consider to be a good content, you can take it somewhere else. The reward pool is the same size everyday. When you spam comments and share other peoples videos with no commentary you are taking away from people who are producing original content. It's unfortunate that you are apparently unable to see this, but if that's the way you feel then you should definitely power down and go somewhere else. We absolutely don't need that crap here. I have shared youtube videos on steemit before to add to a long form post that I was writing, but that is totally different than what you are doing. If you want to change your behavior back to how it used to be, I'm happy to have you here. Sorry, if you consider my actions harsh, but we have to spend a lot of time fighting this type of bullshit. I thought you were someone who was here to share your original content so you weren't even on my radar. I was pretty blown away when I saw what you were doing. Even more so now that you are trying to defend it.
