The internet is not free -- you are the product
Marginalized people are targets online

If everyone is secure, spies must work harder

5. Threat Modeling
When Conducting an Assessment, There are Five Main
Questions you Should Ask Yourself:
1. What do you want to protect?
2. Who do you want to protect it from?
3. How likely is it that you will need to protect it?
4. How bad are the consequences if you fail?
5. How much trouble are you willing to go through in order to try to prevent those?
See "Surveillance Self Defense" (ssd.eff.org) for more

6. What is 'Doxing' (one x dammit)
“Doxing is the act of publishing someone’s personal information, of which there
would be a reasonable expectation of privacy and dubious value to the
conversation, in an environment that implies or encourages intimidation or threat.”
-Crash Override Definition

7. Basic Concepts
Create layers around your identity. Create false identities.
Think about what you share.
Think about where and how you share it.
Take precautions in advance to prevent future doxing.
When in doubt, don't share it in the first place.
