It's just a flag, they collect the data, but won't ban on that data alone. (That's just my guess though.)
Honestly, jagex isn't that retarded. They're not going to let us know what got us banned. (Just my theory btw) If I were them, I would just collect a list of all these flags, albeit via client, mouse, ip, or any other detection method, put em on a list and only start banning them when they've been in that bowl for a while. just grab a random number of accounts and pce them out of the game.
Otherwise we'd just be able to determine what gets you banned via trial and error by editing pieces of code one thing at a time, almost like a super long and frustrating game of mastermind.
