GitHub Reddit and Platform Privacy Checkups
Settings on accounts YOU control — then inventory YOUR GitHub/Reddit on
Visual · platform_privacy_self
Privacy checkups on YOUR accounts.
Opening
The cheapest OSINT reduction is a settings page you are logged into as yourself.
GitHub search and your GitHub privacy/security settings show emails in commits, public gists, and forgotten forks. Reddit account settings hide old usernames poorly if you posted a lot. Other platforms have “privacy checkup” wizards. This lesson is you logging into YOUR accounts and writing what is still public. It is not scraping someone else’s GitHub org, not Reddit-stalking a classmate, not using GitHub search for a teacher’s private email. Original Cyberlium. GATE 192.168.0.1. Operators like site:github.com "YOURHANDLE" still apply. Next: Wayback and Cached Copies of YOUR Pages.
1. GitHub: search YOUR handle, then open YOUR settings
On github.com, search YOURHANDLE as yourself. Look at public repos, gists, and commit emails if you pasted them. Then open Settings → emails / privacy / security and write whether commit email is private.
GitHub search against a classmate org you do not belong to is out. ; do not confuse a router with “source intel.”

Windows: Built-in (PowerShell: Invoke-WebRequest)
═══ COMMANDS ═══

2. Reddit and other checkups: logged in as you, or skip
If you have a Reddit account, open reddit.com/settings and note whether email is shown, whether old posts are findable via site:reddit.com "YOURHANDLE". If you have no account, write none — do not browse a classmate’s profile as “practice.”
Repeat the idea on any platform in your scope (game, blog). Privacy checkup names differ; the job is the same: reduce what YOU publish.

3. Fix on the platform; do not “OSINT” a stranger’s settings
If GitHub shows YOUR personal email in a commit, the fix is GitHub email privacy and git config on YOUR machine — not a tool against someone else’s repo. Record one fix you will make.
Wayback next: even after you fix, archives may remember. That is a separate honesty.
4. What you ship: a logged-in checkup on platforms YOU own and one fix
GitHub search + settings for YOUR handle. Reddit/other only if yours. One concrete privacy fix. No stranger profiles. DEMO GATE. Notes 600.
5. What you record before the next lesson
Date. github.com/search YOURHANDLE. one_fix. File t12-m03-l02-platforms.txt chmod 600.
6. Wrong vs right: strangers vs identifiers YOU own
Worked failure — same OSINT word, opposite target. Right never needs a classmate or a dump site.
Wrong
GitHub-search a teacher’s email. Reddit-stalk a classmate. hydra a login because privacy settings annoyed you.
Right
Check YOUR settings. Write one fix. Next: Wayback and Cached Copies of YOUR Pages.
Mission: privacy checkup on accounts you can log into
1) / STOP if router. 2) GitHub search YOURHANDLE and open YOUR email/privacy settings. 3) Reddit/other only if yours. 4) Record one fix. Never classmate profiles.
