A better way is to just list your email address and accept that you will get some spam. My email address is already in plaintext on many webpages and WHOIS entries. It's not that big a deal.

I have my email address open on most websites I've designed and programmed for decades now, and I don't receive more spam at these address than on at those addresses which aren't public. Spammer harvest for years now using many channels: buying addresses, hacking databases, using viruses stealing complete address books from people.

Using images as anti-spam measure really gives you a lot more problems than benefits (except you'd use random single-usage addresses).

Don't obfuscate, but fix your spam filters or switch your email provider. What helps a lot is server-side moving of detected spam emails to your junk folder and looking through this folder from time to time.

The only measure I use is a email that is invisible email that adds the sending host to a blacklist right before the plaintext email.

Also a great way to prevent people who have to use screen readers from seeing it.

I have a few domains with public whois, the spam from that today is significantly less than it was when I first registered around 2000. The paper spam is almost zero, just a scammy registrar every once in a while. Email spam is probably less than one a week.
