While exploring browser-supported Unicode characters, I noticed that apart from the usual @ and . (dot), there was another character that resembled an @ sign (0xFF20 or ＠) and various characters that resembled a period (I think 0x2024 or ․ is closer, but feel free to argue).
I’m wondering, if one could use this as another way of email hiding. It’s almost as easy as the foo [at] bar [dot] com technique, with the advantage of being far less common (I’ve never seen it before, so there’s a high chance that spambot developers haven’t either) and I think that the end result is more easily understood by newbies. To encode email@example.com this way, we’d use (in an html page):
and the result is: foo＠bar․com
I used that technique on the ligatweet page. Of course, if many people start using it, I guess spambot developers will notice, so it won’t be a good idea any more. However, for some reason I don’t think it will ever become that mainstream
By the way, if you’re interested in other ways of email hiding, here’s an extensive article on the subject that I came across after a quick googlesearch (to see if somebody else came up with this first — I didn’t find anything).
