The best way to avoid fraud is to become smarter oneself. It is not that hard to detect once you learned some survival skills. Sorry, but criticising someone as disrespectful for helping people to learn survival skills sounds damaging. A little like not telling your children about sex and condoms because you don't want them to have sex.

Shit will happen. Better be prepared, and better help others prepare. Stop criticizing people who try to help.

PS: He also didn't say that it isn't fraud. He said that besides fraud there are a lot of other ways a video you made could be used in other ways than you intended.
