Tips on recovering accounts.

Hi Sythe users.
I play rs now since 2005, and i made alot of accounts.
My very first account was named 'Boyke109'.
I remember it all clearly, i was laughing about those stupid people who played runescape in my class.
Laughing at them, for playing such a noob game.
I had never tried it, and was just saying that because i wanted to be 'cool', like the other guys.
On a day we had break, and i needed to write something down in the class, one of those people who played runescape walked in, to grab a football, for playing outside.
He said, why are you not making fun of me now?
I said, well, i never played RuneScape, or tried it, i just think its stupid.
He offered me to go to his house, to create an account, and see how things go.
I wanted to have the name Boyke, but it was already in use, so i picked one out of the suggestions.
I played for a while there, and i liked it.
I kept playing, but i was soooo scared that someone was going to hack me, i changed passwords every day.
So i forgot one on a day, and i didnt try to recover.
I quitted for 2weeks, and made a new account.
Now, like 6years later, im thinking, it would be sooo awesome to login to my very first account.
But the problem is, i dont know the recovery's i set myself.
All the passwords are cleared out of my mind, and i created the account at a friend's house, and my friend moved away.
I dont know the ISP.
Also it was never member, and in that time you didnt have email sets, so none for that.
So basically, i got like no info for recovering, but i am the real owner.
Jagex moderators say the only way to recover is via the recovery system, so im like screwed.
Any other people got tips on recovering very old accounts?
I would really appreciate it.

Thanks for reading, and do you have a story like this, how you started playing runescape, i would love to hear that
