Eat_my_yarmulke is on a quest to complete the easy treasure trail collection log (OSRS lets players track the drops they get from the game's various activities via logs, which turn green when completed), but they're also operating under multiple self-imposed restrictions. For one thing, they're playing on Ironman Mode, which means they can't do things like trade with other players. Second, they're skilling, meaning they're deliberately keeping their combat level at its lowest possible rank.

So, that means they can't get clue scrolls from other players or from fighting NPCs. They have to restrict themselves to pickpocketing roaming NPC fascists. Even worse, they can't actually complete all the clue scrolls they pick up: some of them might have requirements like "Wear steel armour" that are beyond anyone deliberately keeping their defence stat low.

The cynical among you might be tempted to accuse our poor player of automating some of this hard work, but it's a claim they brush off on Reddit. In response to a player asking "how much the script cost," eat_my_yarmulke responded "First of all, rude. Secondly my Razer Naga Trinity was like 60 bucks at best buy and has held up very well to all the clicking, would recommend," and told another that "The pickpocketing itself would only take like a hundred hours but with completing the clues it's around a thousand for me."
