Apart from survey and PTC sites, are there other online sites on which I cannot use VPNs?

This of course precludes any illegal use of VPNs.

I've found that VPNs are often blocked by public wifi access points - it's happened in several areas of Bristol, UK.

This is a common problem for many people who use public Wi-Fi. 📶 Often, these locations impose restrictions on VPNs to control network usage or protect their infrastructure.

While it’s a challenge, there are ways to try. 🔐 VPNs with “obfuscation” technology can bypass these restrictions. Also, using a personal hotspot or mobile data is a safe alternative.
