Wallhaven tags do not always filter out NSFW images about variety HOT 3 CLOSED

First, that is not really NFSW, you need to use a API key to get that kind of categories.
Wallhaven allows filtering tags so you can allow and deny terms. For example I use: +nature -woman -people -supreme to get nature wp.

Hmm, perhaps I will try that. As for it not being NSFW, I would argue that images of scantily clad women (or in some cases, lacking clothing whatsoever on that website) is definitely something that I wouldn't want to display in a work environment.

If you configure just search keywords, Variety uses the most conservative filter for purity (just "SFW"), When you have defined a full URL, Variety shows whatever Wallhaven is serving. In Wallhaven you can customize the Purity level before pasting the URL in Variety. Closing.
