I would like to check if alts have already learned a spell/tradeskill taught by a particular recipe item.
There seems to be no other way than to maintain a database linking recipes to what they teach.
https://www.curseforge.com/wow/addons/libcraftinfo used to do this but has been abandoned for years.
In his last post of 2013 Thaoky implies that he is doing some datamining of wowhead.
Was he talking about some kind of webcrawler? Modern wowhead will surely have captchas in place to prevent such things.
Any other ideas how to build such a database?
