Every time you post, your CURRENT Internet address is stamped on that post. Some people have an IP that very much changes (dynamic IP, and/or they use a VPN). Others have a static IP that never changes.
Either way, all CathInfo posts are now considered and all IP addresses collected, so that ANY of these addresses won't get "caught in the net" by mistake.
While fishing for tuna (malicious attackers), I unfortunately caught quite a few dolphins (legit CathInfo members) in my net.
My net now knows how to identify a CathInfo member, basically. I found a good way to do it.
