Youtube antiscam idea

Most probably not what happened. The Reddit poster retracted most of their allegations in https://www.reddit.com/r/CryptoCurrency/comments/t2cdhj/apology_to_charles_hoskinson_and_rcc/ and @Colin_Edwards posted an in-depth analysis in Sundae Swap Launch Forensics: "Queue Jumping" (both already linked above).

Yeah, well, they use lots of words for not much content.

They say pretty clearly here that your ADA were moved to an exchange and the last holder is not the scammer, anymore.

While it might help, they effectively say here that your bank should have prevented you from buying cryptocurrency in the first place. Interesting.
