Did you ever use ICQ back in the day? a lot of people will be like IC-What? not many people will know what it is. But if you grew up in my generation it was the first ever popular instant messaging program for the masses and it was written for both windows and macintosh computers. A lot of people stopped using ICQ in the early 2000's as there were other programs such as MSN (MicroSoft Network) Messenger/ Windows Live Messenger and others.
Back Then a lot of people simply created an account (or multiple accounts) used the program, and when ICQ started dying, they simply uninstalled the program and hoped the ICQ Company would die or fade away and the servers with their account info go *poof*. Apparently I discovered the later part to not be true.
Big surprise, ICQ still exists, its been taken over by a russian company, and still actively being used today by people, not sure who these people are but they're people using it to this day, strange.
I had a 6 digit ICQ UIN number back in the day, yea was one of the early adopters. I actually had recorded that number somewhere and recently came across it when i was going thru my stuff, I went to the website and tried to login and guess what password my 19 year old self would have tried to use and what do ya know it WORKED. All the personal information I had entered about my self was still there, my old now defunct email address was there, a profile photo with a picture of me too. Wow, this would be a great way for hackers to get dirt on someone. I put in a request to close my account, and was notified it was closed. I even tried to re-log back in to prove it and it was disconnected, phew, a huge sign of releif
The moral of the story? next time you lose interest in one of those chat or IM programs, remember that by deleting the program does not mean your data goes a way. You must actually put a request to delete your account too. who knows, the site could have a major data breach and who knows what info they could obtain about you, or even the 19 year old version of you, its still personal data and its in the hands of the bad guys. remember that.
