SpamLookup Link Filters
(Reprinted from the Six Apart Movable Type 3.2 User Manual.)
Link Limits
SpamLookup can be directed to count the number of links included in a comment or TrackBack. High numbers of links are almost always indicative of spam whereas items without links are almost never Junk.
There are three link limit settings which are pretty self-explanatory:
- Credit feedback rating when no hyperlinks are present
- Moderate when more than link(s) are given
- Junk when more than link(s) are given
The first actually contributes a positive score (non-junk) to the final score. The last contributes a negative score. The second does not contribute to the junk score but instead directs Movable Type to hold the item for approval.
Recommended settings
We recommend that all three tests be enabled and the scoring tests be set to 1. We recommend that you moderate with 3 links and junk with 10.
NOTE: There is a typographical error in the SpamLookup text. Where it says "Moderate/Junk when more than N link(s) are given" it should say "Moderate/Junk when N or more link(s) are given".
Link and Email Memory
When you receive a comment or a TrackBack from someone and publish it, there is a very strong likelihood that future contributions from that person are also not spam. SpamLookup can be directed to contribute a positive (non-spam) score to:
- Comments with an previously seen email address
- Comments with an previously seen URL (in the URL field, not in the comment body)
- TrackBacks? with a previously seen source URL
This credit only takes place if the rest of the item is devoid of other URLs, which protects you in many cases from a spammer trying to submit one good comment and they follow-up with a lot of spam comments.
Recommended settings
We recommend that both tests be enabled and their scores set to 1.
