This is completly false
As soon as i read this, i knew this just isn't true:
Jagex would simply not ask for money to unlock an account. Debate me all you like on this point, but its plain and simple. They will not take / ask for money.
Secondly i would like to point out that those files that runescape stores on your computer aren't made when you make a runescape account. They are downloaded when you load a RuneScape world.
If you choose "Unsigned Java", these files are not loaded onto your computer, and that is the reason you have to completly download the game code each time you use unsigned java.
Thirdly, ill just point out that the packets sent from client to server and vice versa are encrypted, so even if it were as simply as sending :item 234 etc it would have to be encrypted.
The more i study that text the more points i find to prove its complete bullshit, anyone here with any knowledge of Java will agree.
