GMail Spam Filter

Did anyone notice GMail's spam filter failing to catch a lot of spam the last days?

A week ago, it would catch almost every spam mail targeted at my address. During the last days, I had to clean up my inbox a lot. Have the spammers finally found a way to defeat GMail's filtering, did Google change its algorithm or is this just some strange coincidence?

no. I've had no spam with GMail.

No problems here either, there's only a few spam mails every day Google doesn't catch (and I'd say a few every week they catch even though it's not spam – but I don't check my spam folder frequently enough to know for sure).

Thank you.

That's strange: Today I had again about 10 spam mails in my inbox, 5 were filtered. Is the Gmail spam filter user dependent? Maybe I misclassified some spam mails as real mails (or vice versa) and thus confused the filter. Or, maybe, Google is varying its filter among the users to do some testing.

I get over 100 spams a day. GMail fluctuates. Some days I see 2, some days I see 10. False positives are pretty rare. Overall not bad, better than Thunderbird's bayes anyway. The "hot stock tip" types seem to be the most likely to end up in my inbox.

Looks to me as if the stock spam evades gmails filter because the text is base64 encoded. For example:

...
MIME-Version: 1.0
Content-Type: text/plain
Content-Transfer-Encoding: base64
