Wow. Some goober is basically solo mining this coin with an ASIC. What a waste of energy. I bet this dead coin could even be CPU mined if they'd shut that down and get the diff low enough.
That's kind of funny. Maybe you've heard, there's a resurgence of interest in old coins. So this person is taking a gamble that someone will be interested in the future, and there's a decent chance they will be. This wasn't a totally nothing coin either, it was pretty notable among coins of its era (10-12 years ago).
