The only new IP that had not already been banned, that I would have received comment spam, was from Chinanet Jiangsu. I have already banned it.
CN jiangsu 49.79.142.84 p c
If it is already not clear, banning ranges of specific bad internet service hosts makes a lot of sense. These, and others do not go away, are always trying to find a hole in your armour, and are ready every day to spam your web site. Give them no satisfaction and ban their complete IP ranges, or they will show you no mercy.
