It seems better now from a week or so ago. I am back to rarely any spam.
Duff-Man says....same for me. I mean, I was not getting flooded or anything, maybe a couple a day made it through to my inbox at the most, and once or twice a week I'd get those annoying "blank" ones but now it's been back to the normal no spam for me.
This has happened in the past and will certainly happen again in the future. The spammers do something to get through all the filters and it just takes a bit to get caught up again....oh yeah!
