HomeI have found four different types of spammers:
1) Stupid: (all of they are but…) they post dozens of links in the same comment (even images), in addition they can post the same comment many times. They copy & paste the same html code.
2) Moderate: they post very simple comments like “nice blog” or “very interesting article”. They use the keyword (viagra,phentermine) as the name, this way they get high google rankings with the text links. They fail in the keyword as the name, do you know someone with viagra as his real name?. Also the url is another key to catch them!
3) Amateur: very similar as moderate but this time they use a real name as the anchor text (Allan, Steven..) so is more
difficult to identify the comment as spam. The key: just check the url of the comment, it will be something like cheap-prescriptions.com.
4) Professional: they read your article, then post a comment related (few lines),use real names and the urls of their websites are not comercial domains. This way they get a domain with high Google PageRank and then add links to their commercial websites. Be careful with this type of spammers.
