In theory your account could be banned. I've used it on several accounts for going on 7 years and never been banned.

Using Koalageddon or CreamAPI should work fine as long as you don't have to download extra content manually. I've used it for years in multiplayer games and never had any issues.
I trust their privacy claims but if you backup your email and calendar you can just as easily move elsewhere if Proton does go down. Having only one provider can make things a lot easier to manage.
An Nvidia Shield Pro is hands down the best but it is much more expensive. Slap a third party launcher over the top and use it for streaming Jellyfin or Stremio or Kodi or whatever floats your boat. Super responsive and is android-based so you can sideload whatever you want. It also has the most compatibility with most codecs so you'll be able to direct play more through Jellyfin rather than transcode.
I second this. And if you want the pro features, StackSocial has lifetime plans available for $11. It's worked well for me.
It's much easier than trying to play the private tracker game if you are willing to spend a couple of dollars.
I found that Geek paired with DrunkenSlug served me very well for new and old content.
pdalife.com is my go to if I need a paid app.
uBlock Origin is a must for ad blocking. Anything else is just extra flavour. I like SponserBlock and Return YT Dislikes.
I highly recommend crDroid. It's super customizable and has a good battery life / performance ratio.
