Please consider a better version of Jagex Account Guardian, that was amazing tbh.
Thanks for your comment, I recall from the days of JAG that it was actually quite problematic, people forget their answers, typo the answers, use spam answers (jelly1, jelly2 etc.) or set answers that can be easily guessed or obtained through social engineering. At the same time, I also hear people (like yourself) saying it worked well ... as mentioned in the blog we are looking at account security overall so it's good to have that context and feedback and we will explore all options.
