It strikes me that this is enabled by the Internet because it suddenly removes all external checks one cane do in the real world to validate a claim. Back in the day if the Miller boy was in a tragic accident the community all knew and could pitch in. Nowadays I don't know if Eliza who is a 13 year old with cancer is actually a suffering young girl or Fransicojeet in Elbonia.
Ultimately this is the end result of altruism in a system with bad actors and low trust, the generous are taken advantage of by the unscrupulous.
