filter out pastes based on ip using known spammer lists

[stchang]

A quick scan of the logs shows that most spam posts are from known spammer ips. Eg

        "128.70.36.116"
        "93.186.31.112" ; 78462

The site should automatically delete posts from known spammer ip addresses, perhaps using a service like this: https://www.stopforumspam.com/usage
