node package manager


Uses API to compare usernames, emails, and ip addresses to their spam database.


Helps weed out spam accounts during signups. Allows you to check usernames, emails and/or ip addresses against API.

npm install spamcheck
var sfs = require('spamcheck');  // get our object 
// call checkspammer with any mixture of the following properties in the object to check: ['username', 'email', 'password'] 
sfs.checkSpammer({ip: req.connection.remoteAddress, email:}, function(err, isSpammer) {
  if (err) console.log(err);
  if (isSpammer) {
    // user is spam, send back a custom status code with nice message or our spammer. 
    res.send(452, 'You are listed as a spammer and registration will not continue.');
  } else {  
    // user is not spam, register the user. 
    // insert into the db, etc.
