The other tactic seems to be an assortment of fake "Welcome to eBay" messages, and notices of complaints filed for fraudulent ebay activity. I'd say this is obviously geared to getting someone to panic, thinking accounts were opened in their name, and click links. These seem to also be bot-driven, as large amounts of material is just clipped wholesale from the legal pages on the ebay site.
But my favorite spam header is this one from "ownership," touting "enslave: let's temple humanity!"
