Show HN: How I maintain anonymity on internet.

This is pretty naive. All traffic is coming from the same IP address, OS, browser, and browser configuration. If they had the motivation (if it is important for advertising or requested by authorities), all those individual sites listed are capable of linking all your alt accounts.

Also it is feasible that your ISP has the capability of tying all disparate activity across those sites together to the actions of one person. (Again: Same OS, browser, browser config, timestamps, etc)

I don't know what you think you're avoiding. Targeted advertising?

If you want to avoid some cross site tracking (mostly used for creating profiles for advertising) configure Adblock with ad lists and tracking lists and use ghostery.

If you want to avoid censorship or retain pseudoanonymity from most eavesdroppers: use out-of-country privacy-focused VPN services or possibly TOR. Or public wifi. And get comfortable with the fact that if someone is motivated/resourceful enough to find your online activity and tie it all together, they will eventually do it.

If privacy is extremely important to you, avoid using the web.

Multiple accounts for different behaviors/identities, and incognito browsing with DDG, basically. Nothing mind blowing, but a good simple strategy probably beats some amazing tech innovation.

Though I suspect that without Tor, you are passing your ip, which could be used to link you.
