How can people access restricted or banned online services like TikTok when they face geographical limitations?

When popular services like TikTok and other platforms face restrictions or outright bans in certain regions, VPNs (Virtual Private Networks) serve as the primary solution to bypass these geographical barriers. The video presents a comprehensive approach with three different levels of VPN implementation, ranging from simple public VPN services to more advanced self-hosted server solutions. VPNs work by masking your actual location and routing your internet traffic through servers in different countries, effectively allowing you to appear as if you're browsing from an unrestricted region. Beyond just accessing blocked content, VPNs provide essential privacy protection for activities like torrenting and safeguarding your online identity from potential surveillance or data collection.
