korean spam

For the last year or so I've been scanning my yahoo spam for messages that inadvertently slip through. I've probably found 2 or 3 in that period, but the escalation of volume has continued, and I stopped the practice three weeks ago. There are now 1056 in the box, as in indication of the volume, and I reckon 60% or so are in korean (the rest are loans, fertility drugs, porn and cheap software). This makes for a bemusing sort of spam - I can't read it, and the illustrations are so cryptic that they give no help to deciphering the nature of the product. It was the same at DSTC, and just recently they seem to have found my other webmail account. For the moment, my uni account hasn't been picked up to any great extent.
