Toot! for iOS. It lets you add servers you don’t have an account on, and then you can interact easily on that server with any server’s account you’re logged into. I have 2-3 accounts based on different things I’m interested in so my followers don’t get a complete mishmash from me if they don’t want to, and this setup makes it so easy for me to interact and browse as if it’s all the same account.
Nope, and I used to do a lot of Reddit - like several times a day, and usually entire evenings just browsing. I used PowerDeleteSuite and deleted my account, and I use an RSS reader with an adblocker for the 2-3 local subs I truly can’t find the same info for elsewhere. One is a university I teach at, and the only exception I’ve made to this was to create a throwaway to answer a question about salaries and point the person who was hoping to teach to our union contract. Worker solidarity > Reddit drama.
