My college email addresses were created three decades ago and are active today. I could switch back to using one as my primary email address everywhere, and do use it in some places, but the pobox address became the primary one after graduation, before the college address was reenabled.

My Amazon account was also created in the mid-1990s. I applaud the company for making complete purchase histories still available.

I am not sure when my `yahoo.com` account was created but it was in the late 1990s. I have never ever used the address anywhere. It gets lots of spam.

My eBay account was created in the late 1990s. Active the whole time.

I have a low single-digit Slashdot account.

I also have a valid ICQ account from the 1990s, I think, but never used it.
