I use E621 for many reasons, so having the ability to filter out certain preset things without typing -tag1 -tag2 each time would be a nice feature. Maybe it could be a dropdown menu with all of your presets.

Maybe, but it wouldn't be blacklisting. Blacklisting is done client side (e621 sends your browser $PAGE_SIZE (eg 250) items, a script runs in your browser that removes blacklisted items, so you probably end up with less than $PAGE_SIZE items in the page)
In that sense, blacklist presets already exist (Though I don't know how usable they are on mobile; on desktop, you have to not be in fullscreen mode, and then the toggles for each rule show up below the query box on the left). If getting less posts per page is not a big issue, then that might address the issue.
What you describe appears to be 'adding negated terms to your search.. and keeping these in a distinct unit so you can toggle them on / off'. I believe this is technically possible, but would require changes on both the client and server end (at minimum, the server would need to be able to distinguish 'literal' terms from 'expansions', and the client would need to track that information so it could be sent to the server.).
