Is anyone knows any services or communities who share ftp hosting space. I mean there is a lot of webmasters who have few hostings or IPs for their own PBN and do have some extra space on those servers, it would be great to use that space to host some of my sites, same as I would give them space on my servers, in this case we would get bigger IP range of the sites. Is anyone heard of something like this and how does it called. Thanks.
