[weg2g]

Hi, I have written an article about a custom anti-bot. Below is its summary:

In this tutorial, we build a simple yet powerful tool for protecting your site against spam and bots. In brief, I show you create a custom anit-bot with PHP and AJAX. You can add it to your forms or just show it to your visitors before they see the form. Anti-bot asks one random question, whose answer tells site visitors apart from bots. Two-three layers of randomness are applied to questions so that it makes them extremely difficult for bots to guess or bypass. At the end of this tutorial, I will give you 10 practical tips for taking my anti-bot script to the next level.

My tutorial has 1,800 words, so do need to add to it? what are next steps? Also, I do not know how markdown text works.
