don't spam the territories with meaningless links that you don't even open and read them, you just share them because you saw them in other forums or groups. Select very caerfuly what you post. Remember: YOU PAY TO POST! If you post a link of a video, document, article, guide etc, at least put some words attached to that link. You have that option in SN post, damn it. How much time cost you to put your own words about what you share and show your opinion or vision about what you post. In that way people could interpret it correctly your intentions and also engaging with you in a discussion. Discussing create good content.
Context-free linkspam posts are one of my bigger pet peeves here. Seriously people, follow Darth's advice! If you can't tell me why I should click on the link you posted (or at least why you found it interesting, even if I might not), you're no better than @hn.
