obscuring email addresses in posts

I help a music magazine manage its wordpress powered site. They have a contact form to hide their own email address but this is for the bands they cover.

Each month they may highlight 40-50 different bands and within each post they list a contact email address. We don’t want to make millions of contact forms, one for each band multiplied by years of work = too much.

In the past they have been using something called email obfuscator, but it appears it is no longer being developed so they need a new solution.

The easiest thing for them would be that their writers could just continue to write as normal and include the email address as normal, because they copy and paste it no doubt from the bands info, and that somehow it is hidden from view.

I know there are sites where one can go to enter a valid email address and get an encoded version, but that is not scalable.

Any other plugins or just creative ideas to use?
