I've heard multiple people express distrust at giving a third party website their login credentials. I trust the WefWef team, but their concern is understandable. So I decided to host it myself!
Made a few minor changes to the code to lock it down to only login to my instance.
I doubt wefwef would be folded into Lemmy, but Elk is deployed alongside a bunch of the major Mastodon instances, including universeodon.com (elk.universeodon.com)
