This thread is most likely going to be the official "cyberix cost transparency thread":

Cyberix costs 8.70 euros/month + 2 euros IPv4 + $15/year domain. We pay around 12-15 dollars per month, and ~$180/year total. Cyberix doesn't really receive donations (and there isn't any extreme begging going on outside of the home page), so I've been exploring the idea of trying to set us up with a privacy respecting advertising service.

Costs are pocket change (not to me!) and I am also assuming advertising services make it pretty easy to rack up payouts up to 15 dollars within a month without any issues.
I am not interested in using privacy violating services and will try my best to find advertising services that respect user privacy and won't immediately crash old browsers.

I'd like to know what your thoughts are on this idea and how you feel about it. I'll most likely implement a checkbox in the Settings page that lets you prevent advertisements from loading at all on the site if it's really bad. I just need ONE person to throw me $15/month, whether it be donations or advertisers. If you hate this for some reason, feel free to send donations (crypto or fiat) and you can save us from exploring this kind of territory. Also, related to donations, I might add a progress bar to the top ("$8 of $15 donated this month") to make it more clear as to how much funding Cyberix needs to simply stay online.

Is there such a thing as a 'privacy respecting' ad service? If you find any, please share them, it'd be like seeing a unicorn.
I'm not in a good position to donate right now because of unemployment, but I have a job lined up, once I'm in I'd be happy to contribute.

They seem to be the only ones that I'm aware of that aim to respect user privacy

Here's an idea: Keep the donation banner goal, but if it hits 15$, disable ads sitewide for EVERYBODY.

From what I remember, your site needs to have a certain number of monthly visitors in order to qualify for advertisements. Different advertisers have different requirements.
