WTF? We can't put a simple text link to our site in our sigs?

A moderator changed my sig to say
"please re-read the rules regarding signatures".
Now I reread the rules but I'm still confused.
My signature consisted of my name, my email address,
and a link to my Strongbox security software site.
No tables, no colors, no buttons, nothing.
I'm even fairly sure that you all know that Strongbox
is my system and I'm not advertising
for someone else because if I remember
correctly both Greenguy and Jim use Strongbox.
Or maybe just Jim uses it, but anyway,
what's up? Are we not allowed to put our
URL in our sig any more?
