1. If there are clear spam posts, report them. Save their links so you can track whether the mods respond. You may find here that they're not inactive after all, in which case the problem is solved.
2. Reach out to the mods, in a post asking to be added to the mod team. Again, save the url to track whether the mods respond. You may find here that they're willing to accept help and add you as a mod, again problem solved.
3. If reaching out to the mods as described above fails, you need admin help. Post in !moderators@lemmy.world or email admin@lemmy.world with the results of 1 and 2, along with any violations of the moderators guide pinned in the moderators community.

The admins generally won't intervene until you've made a good faith attempt to coordinate directly with the mods and documented a clear case that they're unresponsive or malicious.

I went to c/technology to see what's going on. enu is the only inactive mod I found.

Hey @breadsmasher@lemmy.world, not sure which spam you are referring to, but I am one of the mods of !technology@lemmy.world and we do our best to remove any spam we see or that is reported.

That being said, there have been times when articles get posted that people report as "spam" that we do not deem to be. If you could provide an example of one we have not removed, I will review it with the other mod and figure out why we did not remove the post/comment - but typically this happens because of the above.
