Mine was in the 3.5 million range. My roommate at the time had a 6 digit number and didn't sign up that much before me, I remember it felt wild that they had grown so quickly. And then not long after that it was all 8 digit numbers.
And also yes, the last time I looked, my account was all cyrillic.
I remember a lot of low number ICQ accounts being taken over back in the day, including my own and several security-minded friends. Because of how prevalent it was and how it was the only account we'd had compromised we assumed they found a flaw or had access to reset passwords, or could social engineer support etc.
It's good to finally know there was a critical flaw like the one in OP that was likely used.
In my case because I use it as a random seed or parts of it as PIN, cause I will never forget it and it's "secret" enough.

Mine was 8966646, which is cool because it has 666 in it.
Mine also began with a 2. It was 279866. My girlfriend’s was slightly lower, as she introduced me to the new service. We both felt like pioneers in those halcyon days.
Mine was quickly usurped by a Russian hacker. The profile was replaced by Cyrillic writing. I never knew how they did it. None of my other accounts or socials have ever been usurped like that!
