Like every other site out there, social media networks track their users via IP addresses. This is the first pain point of using a public proxy. If you're using it, someone else is using it too, so you'd end up banned. That means creating a new account, building a following from scratch, and looking for a new free proxy. That's a lot of trouble to go through.

More importantly, many of these free services are often operated by scammers who are only after your personal information. By using a free service, you trust them with your sensitive data (like login and payment information), which could easily end up on the dark web.

Free proxies are often extremely slow because multiple users share the bandwidth. Most of them are also riddled with ads and present other limitations. Connecting to social networks takes ages, which is a waste of valuable time you could spend promoting your business.
