I want to create some filters for my Mastodon account to hide certain content.

For example I want to hide all posts that contain spoilers for a game. I can’t just add the keyword “spoiler” or “leak” to the filter because that would hide them for any game obviously. But how do the filters in Mastodon work when I add multiple keywords to one? Do they act as logical AND or OR? So when I add “game name” and “spoiler” as separate keywords to a filter, do I hide every post that contains “game name” or “spoiler” in it, or do I only hide posts that contain both keywords.

The UI in Mastodon doesn’t really make this clear tbh.

Edit: And do the filters only apply to non-followed accounts or to all?
