concealing email addresses

[N. J. A. Sloane]

Dear Seqfans,

I am thinking of disguising all the email addresses
in the OEIS to stop spammers using them.

When we discussed this last November, three methods emerged as the
most promising candidates.


METHOD 1
The best suggestion (in my opinion) came from Gordon Royle. 

He suggested making two gifs,
one for "dot" and one for "at",
and replacing (say)

        gordon at csse.uwa.edu.au

with

gordon<img src="at.gif" alt="_AT_">csse<img src="dot.gif" alt="_DOT_">uwa<img src="dot.gif"
 alt="_DOT_">edu<img src="dot.gif" alt="_DOT_">au

Let me repeat that last line with a space
between each character, in case some mail readers
make a mess of it:

g o r d o n < i m g   s r c = " a t . g i f "   a l t = " _ A T _ " > c s s e < i m g   s r c = " d o t . g i f "   a l t = " _ D O T _ " > u w a < i m g   s r c = " d o t . g i f " 
  a l t = " _ D O T _ " > e d u < i m g   s r c = " d o t . g i f "   a l t = " _ D O T _ " > a u 

So the %A lines (and anywhere else an email address appears) would
look like 

%A A012345 Gordon Royle (gordon<img src="at.gif" alt="_AT_">csse<img src="dot.gif" alt="_DOT_">uwa<img src="dot.gif" alt="_DOT_">edu<img src="dot.gif" alt="_DOT_">au), Jan 01, 2000



METHOD 2

Replace 

     gordon at csse.uwa.edu.au

with

gordon_AT_csse_DOT_uwa_DOT_edu_DOT_au

  

METHOD 3

Replace 

     gordon at csse.uwa.edu.au

with

gordon at csse dot uwa dot edu dot au

I think it is time to actually implement one of these methods.

What do people think?
