APRS Link to Winlink2000

I'm trying to understand why my I-gate is getting packets from WLNK-1. It appears that WLNK-1 (no call sign?)
is in Halifax, NS! Why would these packets route there my system?

That is the APRS link to the WinLink 2000 system. Hams can preregister their callsigns with the WinLink system and use the APRS system to check and/or pull emails off the system. It's actually a great system that gets very little use.
