I believe this is the link to my user page:
When I first created my account on this site (2 days ago, I think), it showed that I had played 6 puzzles, and had completed 4 of them. This was before I had played any puzzles at all! I thought it was a bit strange, but if I looked at the "This Month" stats, those were correct.
Well, it's three days later, and clearly my stats page is being confused with someone else's. The stats in the tab for "This Month" are correct (for example, I've finished every puzzle that I've started), but everything else on the page is wrong. They change at times of the day that I'm not playing (for example at night), which makes me believe that they are stats of someone else.
