I wonder, does Telegram use a mechanism similar to the one described in my post to circumvent blockages?
And as a thought experiment – if Telegram were to use Google to search for proxy servers – for example, by conducting searches for site:*proxy-telegram*, where service providers simply use the needed pattern in the URL, and autonomously rewrite the configuration if the servers answer certain random tests, how could one theoretically combat this? Google seems impossible to ban, intercepting requests to Google also can’t be done (https), Google indexes everything indiscriminately, and there seems to be no reason not to index something like that. You could also set up about five other search engines. Of course, you could flood Google with non-working services, but the app could immediately blacklist such sites. The only effective method would be to achieve the exclusion of the app from the Google Store.
The only downside I see is that Google itself could block such a service for violating usage rules. Like you can’t make automatic requests from applications unless you pay for it. But you could make them not quite automatic, but let the user click a “load and parse” button.
