Jim Browning
(3,5M sub) some what call him a White hat hacker, he himself said he is not on a hacker level.
in his usual videos he "falls" for a tech support scam on purpose and later uses the connection established by the scammer to his pc backwards to look through the scammers files trying to stop more ppl getting scammed and report it to the Authorities
