I had almost forgotten about Coffee, who, at least on Yahoo! Answers, may be a Nihilsock; I was reminded when I saw his user name come up yet again on WikiChecker's recent queries. I'm inclined to think that on Wikipedia, User:Coffee is a main account rather than a sock account, and for Yahoo! Answers Coffee has given permission to Nihiltres to have an account in his name, also signed off with saying "I'm an administrator on Wikipedia."
At the top of Coffee's user page on Wikipedia, there is a banner that says "Coffee has a real life, therefore Wikipedia isn't his main concern. He will take his time getting to queries." The banner has the Air Force logo. Notice how he doesn't say "I'm in the Air Force." You're supposed to jump to that conclusion. Frankly, I think it's disgusting to pretend to be in the military, especially these days when the National Defense ribbon is too often earned together with a Purple Heart.
And if Coffee is really so busy in real life with the Air Force, where does he find the time to create the most sophisticated Wikipedia user page I have ever seen? Maybe you don't find that convincing enough, since he hasn't edited his user page in months—oops, I mean days. Then consider this: As I write this blog entry, Coffee's logs page (which you can get to by clicking the "Logs" link on his user page 'toolbox') has at least 50 deletion actions performed today (or maybe last night, I get confused by Wikipedia's use of zulu time sometimes). And if you look at his user contributions, you still see a great deal of contributions for today.
You know, if I was as "busy in real life" as Coffee is, I would be able to write daily posts for this blog.
