IMO the RTL video served a double purpose:
1. it brought the idea of a "hoax" / "fake" to a broader public since main stream media news picked it up
(the children knew already because they saw "the ghost of Neverland" on CNN)
2. at the same time it distracted many people from hoax/fake again because for weeks or longer it covered the front entries of google and other search engines.
First result: if people thought of MJ death hoax they just got the RTL fake video (a hoax within a hoax).
Second result: only true real believers found their way through to the forums, the youtube`s and other accounts (for the rest of "random public" our activities were kind of hidden).
Third result: this way a close and rather reliable community of hoax believers could have been established without interference from haters or ridiculing non-believer-fans.
Doesn`t that make sense?
