Ok, so you are actually new to the internet. I’ll explain, human to human, human.

A domain name like reddit.com or katcr.co is a registration someone gets for a period of time, at least 1 year but sometimes more than a year. One year, a user can purchase katcr.co and put up their personal website, because their name is Kat Crosby, and they are a company - katcr.co fits so they buy it and put up a site for a year or two. Life happens and they abandon the site. The domain becomes available again. Someone purchases katcr.co and makes a cookie business for a few years, abandoning the site. Someone else buys it later when it’s available and makes a bittorrent site out of it, runs it for a few years. the domain gets siezed and they can no longer use that domain. The katcr.co domain becomes available again. no one buys it.

Someone said they used to go to katcr.co years ago, someone else chimes in and says “that site doesn’t exist, you’re a liar”, and then someone with more understanding of the internet sends an archive.org link.

Why archive.org? It’s the only site that does this thing.

What is the thing it does? It will, and has over the years visited websites and saved snapshots of it. Archiving it, if you will. You can then go to web.archive.org and enter the domain name of any site and it will send you to the link you’ve been given a few times. This link is to a page that shows all the times archive.org has captured a snapshot of that link. It allows you to view that page (usually just text, usually missing a lot of content like images and external files) as it was at that time.

In this case, the existence of the link immediately disproves your argument.

In other words, you’re entirely wrong. Both about katcr.co being fake because it’s currently not online, and also about me being a bot.

There is nothing there, but there was. Just check Wayback Machine, for example here from 2018. Whether bot post or not, it's entirely plausible that the screenshot is real. Bookmarks don't magically disappear when the site they point to turns to a placeholder page.

Edit: Wayback Machine seems to have some stability problems right now, you might have to try again if you get a connection error.

How’s the internetting going, champ? Did you figure out how the wayback machine works?
