The author there received an email from one of the founders of the site, from which I shall post excerpts here:
ProLifeSearch website is no more. Here's what happened:
... Sadly, the bottom line is that some of the
web developers we hired for this project left our employ and
changed all of the passwords to the site. This meant that for
months we could not access the site, change the site, or post any
new information on the site...
As we tried to force the new passwords from these developers, the
URL -- http://www.prolifesearch.com -- expired, and it seems some rock and
roll site was all too ready to snatch it up because of all the
traffic we created over the past 2 years.
Legally, the site now belongs to that organization. We have tried,
but we cannot get it back.
