the pedoservice family4love.com has some interesting features for the law enforcement
the pedoservice has come into the news after an article in the British press in which it says that it links pedo's and families that want to give their children to pedo's.
First the site was free but in 2013 it became - like so many pedoservices because this is (big) business - based upon payment (follow the money I would say, this is the most simple method of investigation and in 2013 there was no bitcoin)
Secondly read this post (from the Google search site:familiy4.com
All IP addresses are recorded for security reasons, and will be given to the correct authorized if requested. All photos uploaded should be owned to yourself and"
so here you may find a full list of the IP addresses, you don't have to ask it to the hoster or ISP
thirdly there is much of it in the Google cache because they are not upgrading the server - if it ever comes back up again
now if you insert for example France or another name of a country you may find the discussions between members from that country (in the cache of the link)
so happy hunting because it seems that there are some children that will need to be rescued from couples and swapps that were made through this site - in or between countries
Fourth I would also have a look at this information (referrals for one) oh and the webserver is in the US so it won't be that difficult to get a hand on the server and everything that there is on it. The server has also a mailserver on which you would have to lay your hands on.
and I would surely have an even better look at this site, which seems like a kind of index of incest and pedosite services online
