The goals (initially "raise as much money for charity as you can", currently "Do random acts of kindness") don't seem ill-intentioned, particularly since it was somewhat successful at the first ($1481 for Helen Keller International and $503 for the Malaria Consortium). To my understanding it also didn't send more than one email per person.

I think "these emails are annoying, stop it sending them" is entirely fair, but a lot of the hate/anger, analogizing what they're doing to rape, etc. seems disproportionate.
