Hello, it seems like there's a group that wants to home their content on this instance in order to reach instances that were defederated from their previous instance, but as response other instances are starting to defederate (lemmynsfw.com), or are talking about defederating.

At about the same time this group started making communities on this instance all existing posts on the instance started receiving about 4 downvotes, which is now up to 7, but I'm not sure if this is the work of this group. Is the admin aware of this?
