This type of pattern recognition is a very interesting approach to fingering people, even anonymous ones. I've often thought that perfect anonymity is essentially impossible, mostly because nobody wants to enable it, and nobody is smart enough to pull it off for long enough (essentially have a split personality, from even before the time of beginning the anonymous side). As benmanns points out, that ssh command is unique so far. If voidnull has been talking IRL with people about this, they would be able to associate him with it.
Related to the issue of the postmark, there is also the issue of (potential) fingerprints on the envelope and money. The point is, even if the public cannot find identities, the authorities (almost) always can.
Anyways, anonymity is an odd thing: in the US, anonymous speech is allowed (by court decision), but not guaranteed. The government isn't obligated to facilitate it and businesses aren't forced to allow it. voidnull's access to anonymity rests solely on SDF's goodwill and solvency. And the government could easily harrass them, even if they are overseas.
Which brings up an interesting thought experiment: what would it look like if anonymity were guaranteed by law, how could it be implemented reliably and verifiably, and what would the counter-balance be against illegal activity?
