Okay, lets revise how alog of spam harvesting gets done. Spam spiders crawl through the net, looking for a combination of “something@something.something”. Whether they crawl newsgroups; blogs; eBay; etc. – it all relies on the same principle of searching for the “*@*.*” string [* being wildcards].
So who is the genius that thought up that writing “person [at] ISP [dot] com” would be an effective antispam technique? Now that nearly everyone uses that, spambots simply have to add a new search pattern: “* [at] * [dot] *”. Suddenly, all these people that believed they were protected from penis-enhancing pill dealers and Nigerian scammers find themselves vulnerable again.
Just google the following for an example of what I mean:

I guess I’m being a little too hard. After all, if this idea hadn’t spread, it would of still been an efficient antispam technique. But I’m not so forgiving of the people who adopt this technique today, after everyone and their dog are using it.
This is not a good way to protect your inbox.
What do I suggest? Use variants of this overused original, or use different techniques altogether: obfuscated text with javascript; replace ASCII text with an equivalent unicode character; insert 0px wide gif in the middle of the text; make the email address an image with the text written on it [or even part]; use invisible characters in the middle of the address; etc…
