Seriously. If this is your main instance, set up monthly donations. Even if it's just 1$/£/€ or whatever. Times 16k that's $16,000+/month. I donate to mine every month.
The fediverse is free because someone else is paying for it out of their own pocket. Not because they're collecting and selling your private data. So do your part. It's for the greater good and the freedom of the internet.
