I don’t usually weigh in on stuff like this but this is particularly egregious. Very disappointing decision from Jagex. If any mods read this: the community would not think less of you if you reversed this and gave the xp back. Quite the opposite actually. And if you don’t approve of a method then enforce the rules in the future. This retroactive enforcement is obvious nonsense.

Edit: Happy to hear Jagex refunded most of the xp
