This morning I was forced to ban about 18 users for being obvious spambots. That deleted their content on my instance. Are they now banned on other instances, too? I’m just trying to figure out what the best process is for eliminating these spambots for good before they flood all of our feeds.
Yes, but only from the original community moderators / instance admins the community is on. This happens so a mod removing content also removes that content on any other instance following this community.
If you ban a user on your own instance, but originating somewhere else this will only make posts and comments by this user invisible for users on your instance.
