No, you feeding off of the knowledge is great, the "spam" people are referring to are "ghost accounts" that exist only to post links to articles that get them paid. They don't post a description of the link they are posting and they don't discuss anything else on other posts. the links are not posted for the benefit of the members here or to spark discussion, just to get the guy paid. Effectively it's like when someone sends you an ad to your email that targets one of your interests.
There are people here who use a|n purely and simply as a way to steal traffic for their own personal sites, usually with because their own sites rely on visitor clicks as a revenue stream - because a|n has such a high tolerance for this kind of abuse, they make the most of it and use it as a free advertising billboard. They bomb us with short, contentless posts and want you to "read more here". These people are common thieves and should be treated as such. They are a variant on the conventional spammer - conventional spammers are less repugnant.
These people also invariably start squealing about "free speech" should you call them out in it.
