Hey there.
I'm a member of Project Honeypot. It's a neat project where you can either get a quicklink to a honeypot that you can post wherever, or if you have a domain you can donate an MX entry and/or a subdomain. When a spam crawler (a bot that crawls webpages following every link looking for email addresses or forms to use as comment spam, or a dictionary spammer) finds my honeypot and abuses the email/comment/dictionary it'll log their IP address in the project database. Then they are identified as spammers. At that point the IP address is logged to a database which you can download and add to you IP blacklist so as to not allow spammers to get access.
If you've read that entire paragraph and you haven't already decided that you need to do your part and add at least a quicklink to your website, you are a cold heartless spam lover... Project Honeypot... Seriously, get over there and help me kill spam...
Now that I've completed my honeypot I've been given several "invisible" links...
example...
<a href="http://this.is.an.example.com/example.php" style="display: none;">random-text</a>
...that I'd like to put on every freaking page on my whole blog. I thought about making a widget with this code in it, but I don't want something noticeable.
Where can I stick this bit of code so that it'll be on every page but remain invisible to humans?
