There are already some hacks around that protect the users profile or generate tons of fake-eMails to feed to bots

.
What I like to do is protect every eMail that is typed inside a normal post. Lots of users just type their eMail address without knowing what will happen to them soon...
One way could be to use HTML-Unicode. I'm not too sure if this really is a protection against spam-bots.
instead of:<a href="mailto:
[email protected]">
[email protected]</a>
it looks like:<a href="mailto:abc@def.com">
abc@def.com</a>
There's no more mailto: or @-sign. Any experience with that way?
