Can someone tell me how these things happen?

For a bunch of users, it says that they invited themselves. Like, just take a look at who invited Moin.

That was a bug which was reported here. I tried to reproduce that.

Sometimes it’s one day off, but how does it get off by two days

That was discussed in New User has several days reported as "Days Visited"?
