For some reason the traffic on my blog has exploded. Not from regular users, but because of Trackback and Pingback. The log is full of requests to these to services. I have turned them off, because I don't have the time to fix it (if I felt like doing it in the first place).
UPDATE: I figured out why my traffic jumped. My blog was victim to a spam attack, which added numerous trackback URLs. Unless I figure a way out to get around that (or Dasblog has), I'm not turning on trackback ever again.
