I found this very useful plugin today for WordPress – it’s an email bot obfuscator.
What does it do? It hides email addresses from bots looking to harvest addresses for spamming purposes. It’s not foolproof, but it’s supposed to help reduce the chances of successful harvest.
It’s just one .php file – you install it in the plugins folder, then it will automatically create encrypted links from any email addresses on your WordPress site. It creates a mailto link for your users, but if you look at this source code it’s a big encrypted mess that bots have a hard time understanding.
Unfortunately it doesn’t work with emails that are already set up as links with a mailto, so now I’m going through pages and undoing links…
