>Are these actually real? Do these actually work? All this hackers giving advice on how to hack with Kali Linux or with Flipper Zero with crazy antennas? Has anyone tried to replicate it?

>ib4 host my own server

I am looking at odd ones like:
>skiff mail
>disroot

Currently using protonmail for most of my accounts, but dont want them to have everything on me. Tutanota was cool until I realized their inactivity period is 6 months and now my accounts are deleted and can't remake them due to TOS policy. I am forced to purchase a payed account to unlock my free accounts and I dont like that.

So... any experience with skiff mail (now purchased by Norton) and disroot?
Any other unknown but safe and secure providers?
