Zero Spam

I know that may sound crazy but lately I am receiving zero spam in my spam folder.  I check this folder several times per day to ensure a legit email is not mixed in.  When I do my checks there are routinely at least 10 spam emails and generally they are from the same senders day after day.  However, for the past two days there have been none and I have not changed any settings.

Is anyone else seeing this or do you have an explanation?  When I did a search on the forum I noticed a post from a year ago talking about the same situation.

Thanks.
