I was browsing last night following info about SpamAssasin, then protecting email addresses on a web site from being harvested by spammers. I know I read something about a JavaScript that would hide the address from spammers but still be visible in browsers and usable to visitors. Now, after a good night's sleep I haven't the faintest idea where I was. Can you help?

you all may find this interesting.

I decided to conduct a experiment on one of my "disposable" email addressing starting a few days ago. i decided to see if that "click here to be removed from this mailing list" actually worked. for the past few days i've been clicking on those links for every spam mail i got. in the past week i've gone down from 70+ spams a day, to today when i got 11.

i read somewhere that clicking those links to unsubscribe is a bad idea, since most spammers buy and use the email lists blind without confirmation.  unsubscribing only confirms that the address they have is real and they can put that address on another list to be sold.

i don't know if its true or not, but it makes sense.

I put this in my .htaccess file and it seems to be working so far to block all the email harvesters. The IP addresses are those of confirmed bad bots:
