Honey, I shrunk the font

GWI!ShrunkFont!HTML

  06 April 2003

Description

Use very small (size 1) font to hide bogus text (see also The Black Hole).

Example

Notice in this example how the spammer didn't follow the instructions and managed to leave the instructions in the spam.

<p style="margin-bottom: -20"><font size="1" color="#FFFFFF">Random word of BIG LETTERS with length 1 to 22 TSUTHRXJKVUVBECP</font></p>
<p style="margin-bottom: -20"><font size="1" color="#FFFFFF">Random word of small letters with length 1 to 16 uyswdgueoclrwlf</font></p>
<p style="margin-bottom: -20"><font size="1" color="#FFFFFF">Random word of mixed symbols with length 1 to 27 7y14R484w1m7531X</font></p>
<p style="margin-bottom: -20"><font size="1" color="#FFFFFF">Your text 9, note, maximum length of tag is 255 symbols</font></p>
<p style="margin-bottom: -20"><font size="1" color="#FFFFFF"></font></p>

(This spam also uses Invisible Ink for these words)

There is also a variant that uses CSS instead of HTML (GWI!ShrunkFont!CSS).
