Spam Harvesters Are On Your Website!

Services for Real Estate Pros with Properties Online, Inc.

“If it were possible to redirect the time and effort poured into antispam and antimalware code over the last 10 years, we'd already have colonies on Mars and probably a new form of renewable energy.” (InfoWorld).

We have to agree! Spam now accounts for between 95-98 percent of all email and is not going away anytime soon. The main issue is that current solutions focus not on eliminating spam altogether, but on preventing it from getting into our inboxes. But this causes many legitimate emails to get buried in the spam folder, and also does not solve the issue of spam floating out there on the Internet, consuming bandwidth and resources.

We have recently installed a program called Honey Pot, which works to blacklist spam harvesters. We have been able to report hundreds of suspicious IPs to be blacklisted. While doing this we were SHOCKED at the number of suspicious bots out there crawling our websites.


We have become more aware than ever of the importance of protecting ourselves against spam. Never, ever just put your email address on the Internet, unless you’re willing to deal with an overwhelming amount of spam. If you need to place your email address online, you can either use a graphic that spam bots cannot read, or break the address so that it cannot be harvested by the bots. So, instead of you should type me (at) mydomain (dot) com.

Of course, as we said above, any measures we take to protect against spam are costly and limited. For each IP we report, another one will pop out in its place. The real solution needs to come from IT companies. SOMEONE needs to find a way to kill spam before it is ever sent out. Just imagine how much faster and more efficient the Internet will be without spam!

Try putting a robot text file on your site it should help. It disallows some bots from accessing the site.

If I get one more email about someone from East Timbucktwo wanting to send me $20 million because I am so special...

I wish we had a button we could push that would freeze their monitor or something...

Douglas -- Thanks for your comment! Robot.txt files are a must but unfortunately the bad bots don't always do as directed. There are some interesting tips and tricks in this article: 20 Great Tips to Protect your Blog or Bandwidth from Spam.


Rene - let me know if you find the button - I would like that also ;)

Stopping harvesters, there is a way to use your email address and stop harvesters from finding out what it is. If you like to have your  email address linked on a web page or social networking account, blog post or comments like here you just need to encrypt your email address. This is a quick and easy way to do it for free.

I've been on the internet for about 30 years and don't get much spam in terms of my total email.  I use an email obfuscator to hide my email address in binary, on the page.  I don't know if that has helped yet or not.
