By good advertisers I mean good posters in general, not "good salesmen". Some of the banned people with 5+ years of experience had a better knowledge of Bitcoin than you do so calm down.
I'm going to call you on that one. I have yet to see a single plagiarism case where a casual poster of the forum came here, accidentally plagiarized, and was punished. If people have plagiarized, it was because they came here with the intention to spam. I have zero sympathy for those so called "good posters" that got caught and had signature bans. If you are sufficiently talented to hide your spam in a way that never rouses any suspicion, I have no qualms with you, but I still wouldn't call you a good poster.
Just to be clear, I'm claiming that 100% of people that plagiarize did so to boost their post count intentionally with the intention of escaping detection. That means that they did not value their post enough to read a topic, come up with a somewhat insightful response, and reply. Rather they found a relevant post somewhere else and responded with no thought put in to furthering a discussion.
