Lately I've been receiving spam that seems to have no payload.
No links to knock-off phallicpharmaceuticals.
No promise of promiscuous foreign brides
Nada!
They just have a dozen lines like:
oziuyebjrukdebrrpzewciungdjfapa
So yes, they are successful in getting through my heuristic filters, but to what end? What is in it for the spammer?
