Every day, I get about 150 spam email messages in my main account. As a result, I tend to empty my GMail spam folder every few hours, giving the messages inside only the most cursory of glances. Sometimes, this means that I spot a non-spam message in the split second between clicking the button and seeing the column of messages (most of them hocking dubious pills) vanish. Sometimes, I get so superficial a glance that I can only barely perceive that the message is not spam, without being able to note who sent it.
Such a thing happened a minute ago. I think the name on the message was ‘Eva,’ which could be someone who I knew a long time ago. Given the situation, if you are someone who recently tried contacting me out of the blue, please try again. In the battle against spam, there will always be some false positives mixed among the false negatives.
