We've got the same problem with idiots owning domains before us (primarily webhosts.co.uk)..... there are even people that still use it.. <a href='http://www.webhostsuk.com/contactUs.htm' target='_blank'>http://www.webhostsuk.com/contactUs.htm</a> - odd. I can't see that those guys do much business LOL.
We also use a bit of JS to stop trawlers getting addresses from our pages.... eg....
[code:1]<SCRIPT LANGUAGE="JavaScript">
<!-- We Can't Stand Spam!!
function supportaddress(){
var a,b,c,d,e,f,g,h,i
a='<a href="mai'
b='support'
c='">'
a+='lto:'
b+='@'
e='</a>'
f=''
b+='secura'
g='<img src="'
b+='hosting.com'
h=''
i='" alt="Support" border="0">'
if (f) d=f
else if (h) d=g+h+i
else d=b
document.write(a+b+c+d+e)
}
</SCRIPT>
[/code:1]
....seems to do the trick.
