csharp-antispam

CleanTalk service API for C#. It is invisible protection from spam, no captches, no puzzles, no animals and no math.

Actual API documentation

• check_message - Check IPs, Emails and messages for spam activity
• check_newuser - Check registrations of new users

How does API stop spam?

API uses several simple tests to stop spammers.

• Spam bots signatures.
• Blacklists checks by Email, IP, web-sites domain names.
• JavaScript availability.
• Comment submit time.
• Relevance test for the comment.

How does API works?

API sends a comment's text and several previous approved comments to the servers. Servers evaluates the relevance of the comment's text on the topic, tests on spam and finaly provides a solution - to publish or put on manual moderation of comments. If a comment is placed on manual moderation, the plugin adds to the text of a comment explaining the reason for the ban server publishing.

Requirements

• .Net Framawork 4.5

SPAM test for text comment sample

    public const string AuthKey = "auth key";

    [TestFixture]
    public class CheckMessageTests
    {
        private ICleantalk _cleantalk;

        [Test]
        public void NotSpamMessageTest()
        {
            var req1 = new CleantalkRequest(AuthKey)
            {
                Message = "This is great storm!",
                SenderInfo = new SenderInfo
                {
                    Refferrer = "http://www.bbc.co.uk/sport",
                    UserAgent = "Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.12"
                },
                SenderIp = "91.207.4.192",
                SenderEmail = "keanu8dh@gmail.com",
                SenderNickname = "Mike",
                IsJsEnable = 1,
                SubmitTime = 15
            };

            Debug.WriteLine("req1=" + WebHelper.JsonSerialize(req1));
            var res1 = _cleantalk.CheckMessage(req1);
            Debug.WriteLine("res1=" + WebHelper.JsonSerialize(res1));
            Assert.IsNotNull(res1);
            Assert.IsNotNullOrEmpty(res1.Id);
            Assert.AreEqual(0, res1.IsInactive);
            Assert.IsTrue(res1.IsAllow.GetValueOrDefault());
            Assert.IsNotNullOrEmpty(res1.Comment);
        }
      }
