Indeed, using German proxies is a great choice for working with accounts. The reason is that German IPs are much less susceptible to blocking than Russian or public proxies. When you use a German proxy, your activity looks like it is from another country, which reduces the likelihood of accounts being blocked. It is important to understand that for long-term work, you should only use paid proxies. Free servers are often overloaded and slow, which can slow down work and cause frequent connection breaks. I personally use German proxies from https://proxys.io/en/p/buy-proxy-germany-de because there is always high speed and low ping. Plus, technical support is always in touch, which helps in case of problems with the settings. For working with accounts and various online tasks, such as bypassing blocking or working with advertising, German proxies really justify themselves. If you want stable work, without unnecessary problems, I recommend trying.
