I was trying to find a community about sustainable life and found this shit instead:
https://lemmygrad.ml/c/porninfifteenseconds@lemmynsfw.com - warning, porn videos autoplaying.
https://lemmygrad.ml/c/shavedpussy@pornlemmy.com - no images.
Can they and other communities from porn instances get removed from Lemmygrad? 
They’re not, they’re other instances. lemmynsfw should be blocked as it’s listed as a blocked instance on lemmygrad’s instance list, pornlemmy isn’t listed there so needs to be added. Seems like a problem with search.
