A huge number of users posting on social media are just stealth marketing accounts. They literally make fake accounts with personality profiles (e.g. some guy that's into sports) and they will make regular comments and content. But occasionally they will drop links to promotional content which matches the personality.

I'd much rather they were up front about it. So I really don't get the hate for self-promotion because you're complaining about the one guy being honest in a sea of liars.

If prefer that website owners are appropriately named and share and the community votes on relevance, than the alternative, which is astroturfing links.

What we want is content here. If websites have relevant content to share, let them. If they abuse it and spamz block them.
