Hiding your social data, phone number and email are too much, are you really want to hide everything in this world? it's not possible because you've create ID card and driving license which contain your real identity.
I only hide my financial data because I don't want to get a fake friend or get a problem with many people.
Regarding anonymity, I don't think that OP understands how the Internet works, there's no such thing as complete anonymity, more like pseudonymity. Maybe you can avoid tracking for awhile but if you plan to stay on this forum, it's going to be a difficult thing to do.
There's Tor network, explain to me how you can trace someone location if he's using Tor network for anything?
If you want to use this forum privately, you can
[Guide] Use Bitcointalk (more) privately you can achieve complete anonymous after next few years later.
