I've had a Gmail account since the service was in its early beta and you could get one by invitation only.<p>That was nearly 20 years ago. Over the years, the number of messages in my Spam folder grew constantly - last year, for example, there were some 1,000 messages there, waiting for auto-deletion. I didn't care, as I very seldom saw one in my inbox.<p>Something must have changed in the past months. Now I'm getting 3-4 messages per day and those messages are very obvious spams, that even a primitive mid-Nineties filter would have caught. I keep reporting them as spam, but nothing changes - I get the same messages the next day. Even more infuriating, they seem to be emanating from the same bot, as they arrive in my inbox between at ~10am PDT, ~12pm PDT and ~3pm PDT each and every day.<p>How is is possible for Google's excellent (until now) spam fighting system to miss out on those ones?! I'm reluctant to copy'n'paste some fragments here, as they're so spammy that HN's own filter would be triggered and my message would go straight to HN's purgatory - but, please, believe me when I say they're in the spammiest format one can imagine.<p>Any explanation?
