Try using the Photon front end. For adding and removing mods, it is more flexible than the standard lemmy-ui front end.
it doesn't work from the post listing, but if you go to the post directly the option should show up
If the option isn't appearing [on going to the post], it likely means the user created the community. In that case you could try DMing them and sorting out the matter if they're still active or, in the event they're not, contacting the admins and I think they may be able to handle it.
Edited for clarity due to skipping steps.
Wait....you're saying that your best options are contacting the user, or the admins???
I always was taught that the answer to the question "Who ya gonna call?" Is ALWAYS "Ghostbusters!"
If you haven't resolved this DM me the name of the mod you'd like to remove.
