That’s the basics. I didn’t go deep into why it happens exactly, but yeah, it’s easy to get banned for multi-accounting. So if you especially need this for business promotion, you need a proxy. And preferably a good one from a trusted provider.

You can not only use proxy, but also an antidetect browser. For multi-accounting and web scraping I think it’s a must, and good options, including my preferred Gologin, can be checked by the link https://floppydata.com/best-for/web-scraping/. They have built-in proxies, but you can add your own too. It’s exactly the antidetect browser that allows you to create accounts so each one looks like an independent one with its own digital fingerprint.
