I have no idea why this happens, so I thought I would ask.

Sometimes when I go to Blackheart Hollow there is a string of numbers right above the Welcome (like below)

1241246361

Welcome, Traveler, to Blackheart Hollow.

Why does this happen?

Those are just to fool users who are using programs and junk to detect changes in a webpage. At least, that's what I heard.

I have never managed to get anything from there.
