There are different types of spammers all over the world polluting discussion forums, article directories or classified ads site with spam material. In this article we will discuss about the different behaviors of spammers and how we can prevent them.
Typical spammers:
We can classify spam prevention techniques into the following categories.
- technical bad words
- technical spam filter
- technical email block
Bad technical words:
This is the simple technique used to hide the original spam words that appear on the website. In this technique, you can define a rule to replace profanity with whatever words or signs you want. For example, if someone uses an offensive word, you can define a rule to censor those words with lines “…………” or “xxxxxxx”, etc.
Spam filter technique:
This technique is mainly used to hide user posts that use spam words. In this technique a maximum number of words is defined. If that word count exceeds that post, that post becomes inactive and most of the time requires approval from the site administrator or moderators.
Technical Email Block:
Most of the time, spammers try to master the spam filter technique by putting some extra characters along with the words. For example, if a spammer wants to advertise for sale of puppies on any classified site like muamat.com. he/she can use **Puppy for sale** or
Puppy for sale. In this way, they try to bypass the spam filter. To prevent this technique, you can define an email blocking technique. In this technique, you can define a list of email addresses and you can block the given address from posting to your site.
