Although an old screenshot, this person is still up and about.
What is the scam? Well the Tier 3 Scroll production recipe's.
Firstly, this person YouBuyISell is claiming to be selling a Tier 3 Defense Scroll recipe. When infact, he/she/it is selling a Tier 3 Magic Defense Recipe.
I walk by in Uruga at present day (1 hour ago), and I come across shops selling Tier 3 production scroll recipes for 200s or so.
Dont be fooled!
Some of these recipes can be purchased from the Item Merchant Nina in Elderine! (For fame of course)
