First post here on this site, so hope I am doing everything correctly.
For Daggerfall Covenant side, in the zone "Bangkorai" there is a location called "Silaseli Ruins". In the southern most section of this ruins, there is a Spidersilk and Ebonthread spawn location that respawns instantly when plucked. If plucked repeatedly, will net you 60 or more spidersilk / ebonthread a minute (sometimes 3 a pull, sometimes 4 a pull). Use it to level your clothing skill quickly, refine for purples to sell, or just sell the raw materials. Not as great as the bank dupe and the hireling dupe, but, if those get fixed, we will still have these spawn locations to farm.
To make this one better, if you are on the quest "Conflicted Emotions", you will be in your own little zone, so no one else will be able to watch you, and there are no monsters to worry about.
