Thanks goodness I installed a spam filter on cookedgamers.net when I had the chance. I have to admit I haven't touched the backed of that site in quite a while. After doing some upgrades to the Drupal-powered site and preparing it for a relaunch, I noticed that I had a lot of comment spam in my database. Nearly 60,000 pieces of spam.
So, I went into my SQL database and ran
delete from comments where status = '1'
which resulted in:
Deleted rows: 56779 (Query took 4.2604 sec)
The cG.net comments database table went from being 85MB to 320KB in filesize after the deletion and optimization.
