I don't see how that user can be banned because his post has some similarities with an article on some other websites.
It could possibly have been used for research purposes, and the user took some information from there and other sites.
This just looks like a retaliation, cause this post struck a nerve, this further proves the bias in this forum and how the the lower ranking members are trod upon by higher ranking members.
For God's sake thus is not a content competition and it is not in the rules that you can't pick ideas from sources.

I strongly suggest theymos looks into this.
Maybe it's not the spam posters killing the the group but the conceited high ranking members.
