> if I wrote a series of blog posts in the coming years, you could maybe analyize timestamps to determine my time zone. However, the compiled site shows only the date

When I set up a pseudonym GitHub, I was shocked to find a script that linked the two accounts. The first giveaway is using the same languages. Not as much of a problem with a blog. The second was commit patterns and timestamps.

This is the blog's commits, where you can find an e-mail and timestamps: https://github.com/untraceableblog/untraceableblog.github.io... You know the timestamps are accurate because Tor needs a valid system clock to keep a good connection.

Solution: I developed a gem 'GitFog' to randomly backdate my commits up to 48 hours in the past. More about that here: https://github.com/msjoinder/gitfog/

No, you suspect they're accurate, but you have no way of knowing whether the author was connected to Tor when the commits were made.

That said, GitFog sounds like a useful tool!

I came here to say basically the same thing. If the author uses your gem, the timezone/active timeperiod identification route is greatly lessened.

I actually think the combination of a custom domain and Github makes it much more likely he'll be discovered. Buying a domain means transacting bitcoin, which as others have pointed out, is not foolproof. And Github actually provide plots which make estimating the timezone easy... https://github.com/untraceableblog/untraceableblog.github.io...
