Good OpSec should be practiced by everyone in general:

• If you use your Saidit username in other places, consider all uses linked with respect to how much you've doxxed yourself
• Consider the email you registered to a site with public information, never use an email that links back to your real identity on a social media account. The most common way people get doxxed is using a real email like yourname(at)gmail.com on on a site like LinkedIn or Facebook, as well their shit posting account on a place like reddit, or some other internet forum.
• Assume that most all of your emails will be compromised at some point, make new ones for new sites - it's free
• Never talk about where you work or where you go to school
• Never make arguments from authority, even if you are an authority in a field
• Don't use the same password on different sites
• Have a burner phone you use for social media accounts / emails where required. A prepaid phone in a made up name with 30$ on it will last ages when you only use it for dual factor
• Use a VPN / maintain certain regions of IP addresses on your politically incorrect accounts
• If you want to use social media or the internet for normal purposes have a normie account
• You don't need a VPN on your normie account

Finally:

• If you have good reason to believe you're on a glownigger watchlist, have fun with it. Leave Tor and I2P open all the time as a relay, but don't use them. They'll expend loads of resources trying to decrypt traffic that doesn't exist.
