It would be very hard for me to take that David Wilcock, Corey Goode and/or Michael Salla have been compromised. I do believe that they are all very sincere people, especially Corey who actively promoted the SSP petition. However it is also entirely possible that the Cabal is trying to use the "divide and conquer" tactic here, especially they are so close to the final defeat. This does remind me the what happen to John Connor in the last Terminator movie...
Although I do agree with most of what BP said, I would like to point out that Corey didn't mention explicitly that he went to Agartha. He only said that we went into the Inner Earth. If he did go to Agartha, the next question to ask will be which side he went to, as Cobra mentioned in his in blog on 28th May 2015 that there are indeed a "Light" and "Dark" Agarth network:
"The Light forces have then built their own network of underground cities and this network was holding the Light for the planet in the last 26,000 years. In various modern intel sources, this network is called the Agartha network, the Shamballa, the underground kingdom of Light…
The dark forces have also built their own network of underground dwellings and they have allied with Dracos and Reptilians already living in certain locations underground. They have been keeping the darkness for this planet in the last 26,000 years. Various modern sources were calling this network Shamballa, the Agartha network, the Naga kingdom, the Patala… So if anybody speaks about the Agartha network, you need to discern clearly which network they are referring to."
Nonetheless, I definitely agree with BP that we need to keep Drake on the Light side as he is going to be involved in the genuine intel dump right before The Event happens.
Finally, I would like to say that discernment is now more important than ever, we need to think through information throwing at us even though they are from our trusted sources. Also, we need to stay unite.
Remember: The Cabal need to unite in order to survive, We need to unite to win
