Another place to search for private key candidates would be the outputs of various common PRNGs when they have been seeded with a timestamp (for all timestamps in, say, the past 20 years).
These would look like nice random values (unlike the ones that were recently compromised), but they would be trivial to generate by anyone who knows the initial inputs (PRNG algorithm, seed, maybe starting byte position, etc.).
