I have a hotmail address that I still regularly use for silly stuff. The earliest email I can find under it is from March 2006.

The animations I put on Newgrounds. The Angry Atheist series.

1. AA gets in a rocket and goes up to heaven to fight God in a katana battle. In the end they both get killed by Buddha.

2. AA shoots up a church service and get taken out by an old lady sucking his face off with a plunger.

3. Jesus’s Revenge. The Son of God comes for AA. I think he kills him but then gets run over by a drunk driver.

4. AA drops a nuke on the Vatican.

the oldest one that I can still log into, probably yahoo mail. late 90s. so probably 28-29 years.

I’m no greybeard in comparison to the wizards here, but can still probably log into my webkinz account from 2008. I think they still have a legacy app anyhow lol

I’m sure you can find old forum posts of mine from when I was an internet baby but couldn’t log back in to those, if an account was even required back then lmao

My Yahoo email address is 27 years old.

I would’ve said Elfwood, since I posted some cringey drawings there in the late 90’s. Since Elfwood is closed, remnants of my presence still exist on TOR.N (theonering.net). It was a pre-movie Lord of the Rings fan website, which, amazingly, still has Barliman’s chat room. I wonder if my Battle of Fanghorn Forest poem is still there somewhere 🤔

ETA: so in answer I’d say about 28 years old. If you’ll excuse me, I need to drink some Ensure and clean my dentures

I can still log into my Slashdot /. account, I think. That’s from 1997-98?

My email address is 26 years old.

I’ll probably still have some accounts on obscure forums I can’t remember. But something I still use fairly regularly is my Human Paladin in World of Warcraft, he’s almost old enough to drink and drive (not at the same time).

My Yahoo account is 25 years old I think. My first email address.

My yahoo email address, created in the early 2000s. I receive a yearly reminder on my current email that it’s about to be deactivated due to inactivity, so I log on to keep it alive. No reason really.

deleted by creator

I still maintain a Gmail account from their beta test days. I had to get an invite. 2003 or 4ish? Don’t use it for much anymore, but I still have it.

I’ve been looking for my first Usenet post in 1990, found a few close to the first, but not (yet) the first.

I would not be surprised if there are older posts predating the internet, stored on the Hobby Computer Club FIDO mirrors … assuming that they are still in existence.

Just to add some perspective and context to this:
