• Is it possible to use a hosting service I'm already paying for (strato.nl) and a domain I've already bought to host a Mastodon/Pixelfed instance? All the websites that encourage me to selfhost advertise a new hosting service to me with the price in dollars.
• Furthermore, is it possible to start an account on this instance that can be followed via either Mastodon or Pixelfed and vice versa, or are they just unrelated? I can see accounts from pixey.org on my Mastodon Android app and I know you can post to Lemmy via Mastodon but I'm unsure on how it goes the other way.

Sorry if I've made your eyes roll but we all shat green once.

Edit: very happy with the responses, thanks all.
