Snooker - Lightweight spam detection for blog comments
This crate provides a pure-Rust implementation of Jonathan Snook's spam detection algorithm for blog comments.
As described in the afore-linked post, it works on a points system. Points are awarded and deducted based on a variety of rules. If a comments final score is greater than or equal to 1, the comment is considered valid. If the comments final score is 0 then it's considered to be worth of moderating. If the comments final score is below 0 then it's considered to be spam. Each comment starts with a score of 0.
Installation
If you're using Cargo, just add Snooker to your Cargo.toml
:
[dependencies]
snooker = "0.1.0"
Example
Snooker gives the example comment below a score of -10 based off of the following patterns:
- The
body
has less that 2 links in it: +2 points - The
body
is more that 20 characters long but contains 1 link: +1 point - The link in the
body
contains one keyword considered spammy ("free"): -1 point - The
body
contains one phrase considered spammy ("limited time only"): -1 point - The
body
starts with a word considered spammy when it's the first word of the comment ("nice"): -10 points - The
author
field doesn't containhttp://
orhttps://
: +0 points (unchanged) - The
url
field contains a keyword considered spammy ("free"): -1 point - None of the URLs use a TLD considered spammy: +0 points (unchanged)
- None of the URLs are longer that 30 characters: +0 points (unchanged)
- No consonant groups were found: +0 points (unchanged)
- No data was provided about the comments previously submitted with this email address: +0 points (unchanged)
use snooker::{Comment, Snooker, Status};
let comment = Comment {
author: Some("Johnny B. Goode".to_string()),
url: Some("http://my-free-ebook.com".to_string()),
body: String::from("
<p>Nice post! Check out our free (for a limited time only) eBook
<a href=\"http://my-free-ebook.com\">here</a> that's totally relevant</p>
"),
previously_accepted_for_email: None,
previously_rejected_for_email: None,
previous_comment_bodies: None,
};
let snooker_result = Snooker::new(comment);
assert_eq!(snooker_result.score, -10);
assert_eq!(snooker_result.status, Status::Spam);
