Hey Gen,
Thanks for the reply.
I believe the email should be [redacted] or [redacted] or something along those lines, I had so many emails back then that aren't active anymore. I did try to recover it with email before making the thread but couldn't find the email anywhere.
I should have only logged in from the [redacted], and if I remember correctly the account was created on the ISP [redacted], IP history should contain IPs starting with 3.*.*.* I believe, or a very low number, 12 years is a long time.
I have the same name as my steam custom URL, I've had it since the custom URLs became a thing on steam [redacted]
I also own the domain [redacted]
Thanks,
Ollie
