German proxies for working on the Internet

Recently, I often encounter the problem of account blocking when working with Russian IPs, especially in advertising and betting. I heard that German proxies are better suited for these purposes, since they are blocked less often, and they also work faster. Has anyone already used such proxies? What are their advantages, and where is the best place to buy them? I want proxies to be individual, and I do not want to risk with free ones, since too many people are sitting there at once. Share your experience, please! I want to understand whether it is worth investing in this and how much it comes out to.
