This was a topic that was very important to me years ago. At that time I was spending a lot of time on a "Postmodern Christian" message board, "theooze.com" that went belly up around 2012. But it was an interesting place that was only slightly moderated most of the time. It more or less was almost a kind of Wild West place like Tombstone, a virtual anarchy until somebody really went overboard where a moderator had to delete threads, ban somebody etc. But until then, the law was nowhere in sight.
What I liked about that place was the kind of interactions, discussions and debates you could have. Because they could often be much more interesting that what takes place in what I call the "Christian Ghetto", where all the different groups stay in their little neighborhoods and only talk about various minutia of what canon law etc. applies to whatever situation.
Instead of that there was a lot of "Think Different" kinds of discussions, where lots of people were rethinking or advocating for some kind of position that was much different than what they were raised in. You had some nonsacramental protestants becoming interested in more traditional Christianity and asking questions. But you often had the opposite of that, where others were questioning the need for "Institutional Christianity" and doing things like making threads promoting the Christian Anarchy movement, and lots of people were into things like "House Churches".
Anyway while on the Board I had it in for this one radical author named Frank Viola whose first big hit book was "Pagan Christian" because not only did I disagree with the book (That tries to make the case that the basic liturgical Christian format comes from Paganism) but the author two or three times would come by to promote his next venture and I would do my best to denounce him because he really seemed like a false teacher. Basically he was making his living selling materials to people who want to do "House Churches" especially Charismatics and Anabaptist types, and he seemed to be doing his best to basically proselytize people away from their local body to instead staying home and having their friends over doing a home church worship/ prayer / Bible study meeting using his materials and being part of his home church network.

Oh and I forgot the most important part as far as the OP goes. This guy was a naked Plagiarist. I once was very active studying the "Church Growth" movement when I was looking to a be a Protestant pastor. As a seminary student, but also a former student of the Social Sciences I was very interested in ways to engineer church functions to be seeker friendly, and other kinds of group dynamics that let a small group actually grow into a church. (Their are lots of Social Psychology things that come into play that small church plants have to overcome). Anyway I was very up on books written to help churches have "cell groups" and I owned many of them, and intended to use some of them. But when I read the guys materials I could tell he was directly stealing the various formats, exercises etc. that came from these books! Which would have been fine if he had at least cited them, but he didn't he just advocated doing the various exercises and wrote it in a way where the reader would probably assume he invented it!
Anyway this one time I really confronted him on the plagarism. On top of that he posted a thread on something like a new book on a "Emergent Biblical Church structure". He had a few followers that were interested in this new book he was researching and were looking for some preview type hints. But the guy was evasive, I could just tell that he absolutely knew nothing on the topic (He was just biding his time to hopefully steal from some other Protestant author). So I answered the topic questions from the poster from what I knew Eastern Orthodox theology had the answers and gave them and in detail especially on topics like paradosis / Apostolic tradition but also pointed out that this was the very antithesis refutation to his position on many assumptions (but it answered all the questions of the poster extremely well)!
But I found out like a year and a half later, after I lost track of him and started thinking about him again and googled him, and I found he basically plagiarized me this time! Well technically it was me, summarizing all the Eastern Orthodox theology I digested from reading books by Conciliar press and hearing various Eastern Orthodox church services homilies! And the same sort of thing happened, he got praised by people who assumed that he made all that stuff up on his own. So I was temporarily chagrined. A few years back, I have seen him come out with a "Recommended Reading" list a few years back, and was happy to see him recommend maybe a dozen Eastern Orthodox books on that list so I guess I sort of won in the long run... He is both citing sources, but his teaching has become a bit more moderated as well even though he is still making money from his old books like "Pagan Christianity" that the iconoclasts still buy.
