Something like this is simply people who are unscrupulous leveraging a communications platform that's position is it is open for people to post their own content. I for one don't want communications platforms, that bill themselves as open places to post content, to police people's speech as a matter of general course. There are exceptions but the general rule should be people should be allowed to communicate even if their communication is pyramid schemes, trying to sell you the Brooklyn bridge, get rich quick schemes, etc....
Some people need to learn the hard lesson and we need to stop bailing them out.
