Note that whenever the reason contains the word 'Permaban', it was added manually, usually AFTER the ISP owning the IPs failed to respond to a message sent to their abuse address(mostly after link-spamming in the forum.).
The rest has been auto-banned when one of my scripts caught them doing something naughty...

Where there are gaps in the Id numbering it means I have removed a Ban. (It can happen). If a date or the clock is missing, it means my scripts probably had a little flaw, or I forgot to add that bit of information when I manually banned an address. Time is CET (Central european Time, or GMT+1, if anyone is interested)
