You do not know what you are talking about. To see an ad in Geminispace, you would need to deliberately open a page with an ad. There are no embedded ads. There is also no support for tracking in the Gemini protocol, and no JavaScript and such. But to make it more concrete and practical: Here is a Gemini-to-HTTP Gateway which shows a page which lists Gemini aggregators. As an entry point to geminispace: portal.mozz.us/gemini/…/faq-section-2.gmi You can start there and search. Now, show me a single Gemini page with an ad.
