My GMail Spam folder just hit 20k messages

There is a nice little message saying that spam older than 30 days will automatically be deleted, but as of today, I still have spam from February 25th in there.   It doesn't matter too much to me, I guess.  I am not nearly close to the 7 GB space that they give me for free.   At least I know I am not the only one.  I do wonder if it is an indication of something else going on with GMail.  They have had several rounds of downtime lately.
