NPC Interaction Filter
 

Is it possible to write an addon where you can put NPC-Names via hotkey on a blocklist, wich blocks the interaction prompt while targeting them - so you cant open dialog by pressing the keybind for interaction?

I think it would be possible. I do know that Azurah's can stop you from stealing stuff (in other words, using the interaction button) and I think you can also check what the reticle says.

I stayed up later than I should have writing this so you'll have to excuse the lack of keybinds just yet, but let me know if I'm on the right track here: http://www.esoui.com/downloads/info1623-NoInteract.html
