Okay, not Xoom. Or any server with popups. ^_^'
Actually, I had used Crosswinds a couple years ago
and they did not require ads at all - you might 
try them, although sometimes their servers are 
slow (unless they upgraded). 

Also, while keeping a dummy HTML file on a free 
server might trick their snoopers for a while, 
traffic logs will still indicate if the files 
being pulled look funny (i.e. direct links, not 
to the HTML file). I wouldn't recommend doing 
that because, if your traffic is large enough, 
if you're caught that's that... 

Finally, Drac... ^_^' I'm not a reseller, but if
you're really in a pinch I can offer some of my 
space. It *is* paid for (no ads), but I wouldn't 
mind putting some space aside (I have 200 MB and 
400MB daily traffic allowance)... Oh well. ^_^ 
I'd still recommend creating straddle accounts 
(full ones with working HTML), since that's the 
best way to get around space issues - you'll have 
to find free servers with no ads, though. 

Good luck
