[kakwa_]

There are 2 kinds of spam:

* Nigerian scam type spam

* ads/commercial spam

The first is already illegal, and yes, it's difficult to fight and comes from first world jurisdictions.

But the second is operated by well known companies, most of the time through well known service providers (Salesforce, Adobe...). And these companies do put a lot of personal information in their databases (what did you buy, did you click on a specific link, did you open a specific email, etc).
