Spate of spam

and what is with all this spam I've gotten lately?
okay.. so spam is nothing new, certainly..
but there's been a spate of it from nobody in particular..
that's right.. the "sender" field is blank..
those will go straight into my trash bin..

(along with all the other spam I get..
like this one seemingly originating from France..
"get your free pizza delivered to your door right now!"
I automatically distrust that one.. coz Italy's known for pizza :P)
