SPAM!

I am so tired of getting spam comments on some of my sites. I’ve also tried many anti-spam plugins.

  • Spam-Free Plugin
  • Comment Math Questions
  • Comment Quiz
  • Comment Captcha
  • Double Opt-in
  • Change default comment page name from wp-comments-post.php to something else.

Guess what? None of them work so far. There are company in India hiring real people to crack the CAPTCHA code for spammers. The SPAM-Free plugin only blocks those from your blacklist or known SPAMMERS. Comment Math isn’t working when it always easy to calculate.

Most WordPress spam comments are submit from automated script running on anonymous servers with random forged IPs. So the spammer never visit your website. That really sucks out of my valuable time to fight spam and delete spam comments.

One of my site just post a new article. Within few hours, I got over 100 spam comments with ZERO visit and page view.

What can I do about it?

Recently, I discovered one of my web project build on top of CodeIgniter is having issues with duplicate page views. It only happens to FireFox and Google Chrome browser. It looks just find on IE, Opera and Safari browser. So I keep researching and researching and finally found out that Facebook Social Plugin is hitting the page after the initial page load from the browser triggered by the end user.

I am not sure why it doesn’t happen to browsers other than FireFox and Google Chrome. There has to be a way to prevent this from screwing up my page view counter.

What the heck is this blog post all about? I am warning you that this is going to be a very technical driven blog post.

I felt so funny that this blog got more traffic from search engine to IT related blog posts than to my Internet Entrepreneur Diary or Weekend Confession blog posts. This blog was started with many IT relate topic to records the problems I ran into and the solutions I found. It’s a good time to give it a little update.

Let’s cut to the chase. I am working a new projects that is running on PHP5, Apache 2 and MySQL. I need to get this project done fast and good. So I finally found one of the best choice from so many PHP frameworks. CodeIgniter seems to be the best one fit my needs. It’s very simple and fast. Although it does not support PHP5 OO programming, but it does run on PHP5.

I am using Yahoo YUI Javascript library on one of my client’s web site. The web site is hosted on MediaTemple.net‘s GS (Grid Service) server, which is Linux based web hosting server. My client asked me to move the web site to another Windows 2003 + IIS6 based web server for testing and backup purpose. I have moved the code and everything work fine except the AJAX feature is not working right.

Whenever I set the asyncRequest request, it does not post the data. Instead, it always returns an error about “Length Required”. In other words, the server script do not receive any post data so it return an warning that there is zero data length.
