Ever heard of Project Honey Pot?
It’s an awesome service that’s been around for quite a while now (since 2004!), and is the core part of a community-driven effort to trap and track spammers online, including spam bots, email-address harvesters, and “bad visitors”. If you run a blog (like WordPress) it also tracks comment spam too!
To quote Project Honeypot’s sharing message:
I wanted to let you know about a service called Project Honey Pot.
It allows you to track and help catch spammers who harvest email addresses from your web pages. I signed up myself, added honey pots to my site, donated an MX entry to help the cause and think it might be a service you’d find useful.
At this point, I’ve now donated 141 MX records across 133 Unique domains, with several Honeypots hosted also.
Sound’s like a lot, right? The more donations, the better – If you have a website and/or domain and you (like me) hate Spam, you can sign up and they’ll walk you through getting set up to help catch and blacklist spammers (it’s easy and free!)
