I understand your frustration and I, too, thought that blocking went both ways before seeing your post.
If you encounter someone who is harassing you and attacking your reputation without your knowledge and down voting your whole history, you should gather the proof and contact your instances mods. There’s a very good chance they’ll ban them either temporarily or permanently from the instance. Or contact the mods from their instance as well.
Anyway, I hope this helps.
Honestly, Proton is such a great alternative to Google in so many ways. For email, for the cloud storage, for VPN, and for password/2fa management.
Proton pass can store 2fa tokens using qrcodes just like Google or Microsoft Authenticator. And with the Firefox plug-in, it can auto-fill 2fa prompts. So your don’t have to stress about mis-typing your code or the timer running out lol.
