Four years ago I started a test to see how well different email obfuscation techniques worked to thwart spammers.
My requirements in order of preference were:
- A clickable link.
- Users should be able to copy the email address to the clipboard.
- It should be easy for me to insert an email address on a page.
- It should reduce spam.
Well, it’s been 4 years and here are the results:
|Method (see original post for explanations)||Emails in inbox||percentage of plain text|
|Using plain text||247||100%|
|Using AT DOT||48||19%|
|Using code direction||0||0%|
These addresses all pointed at Gmail inboxes and Gmail deletes spam after 30 days so the spam folder counts can be ignored.
<a> link using ROT13 and the text of the link either a span using code direction or applying the style to the
<a> link itself.
Messy (and unchecked / written by hand) but I guess an email address will not change much so, once the correct code is worked out, it could be added to a snippet or clipboard manager.
