You know this, and I know this. However, many of the regulars don't know what to do or have any idea about how things like this work. I checked the email address of relatives and surprised them with mentioning what sites they registered on. Their response was how did I know they were registered there, and what the first or last letters of their passwords were, etc. At that point they started to panic, and people who panic are desperate and very likely to pay to get themselves "removed" from these databases. People here often blame regulars for not understanding Bitcoin, but they fail to understand that regulars don't even understand the basics of the internet. I would say that spreading awareness and knowledge is the best thing that you can do within your own environment. Not everyone knows how to deal with these things.
