Why are some of my packages sent back to me?

[Danforz]

It started when a trade to a fellow BOTL was sent back to me about a month ago. Now yesterday I had 2 other boxes I sent out (the day before yesterday) come back to me. The "To: xxx" is clear, and my address is only on the return label... who ever processed it seems to have put a sguigly line on the return address... and the "From:" of the return address is covered but everythine else is clear. Any ideas why?
