Modification corrected by my friend SysAdMini at MalwareDomainList (cheers dude :))
.... well, it is only my second PHP script, and I didn't write all of this myself hehe.

Date: 21-11-2008

* fSpamlist and StopForumSpam checks now split, so checking an e-mail address is no longer mandatory

Date: 26-11-2008

+ Code copied to check_spammers_plain.php and modified (mainly including HTML being removed) to allow an HTML free version for those wanting to have the checks in their own software (e.g. phpBB)

Date: 27-11-2008

Date: 01-12-2008

+ Added additional information concerning listings in ProjectHoneyPot

If an IP is found to be listed in PHP, if using the main UI, you will be given detailed information.
If using the check_spammers_plain.php script, you will be provided with it's "simple" listing (e.g. 127.x.x.x)

The 127 address results are;

Octet #1: 127 - static
Octet #2: 0-255 - Number of days the IP was last seen
Octet #3: 0-255 - Threat score
Octet #4: 0-7 - Visitor Type
