I got a bad one.  I tried a few years back to log into flickr with my yahoo account.  No matter what I tried, I kept getting this error:<p>&quot;Hello- new account signups are temporarily unavailable from this network address space used by your Internet Service Provider.&#x27;<p>Flash forward 2 or 3 years.  They&#x27;ve gotta have it fixed by now, right?<p>Nope.
