This is tough without voidnull leaving some sort of clue, or the involvement of SDF ( access logs and mail) and the post office , and/or an very detailed tor exit node analysis. Or of course finding an exploit in SDF's system.
Text/source matching is a no go, if you search for specific words used in the text maybe he has posted elsewhere on the subject of SSH/TOR/SDF, I came up with 2 names (last name withheld since this is a wild guess) Doug and Patrick.
Snooping around SDF shows very little, no gopher setup or usage by username voidnull.

The mail might elude to the fact that he set this account up a week + ago and tested this out before he posted it. So the best bet would be to figure out what was mailed to SDF during the week of April 22nd.
Best bet:
1. Find a security hole in SDF
2. Stake out an pay off someone at Post Office Box 17355
