Is there a way to ban adult websites?

A country blocks access to adult websites based on the IP address. The person still access those adult websites by using a proxy like "tor browser", "Psiphon" browser plugins "browsec", etc.

Is there a solution to ban access to adult websites even if the person uses a proxy?

You cannot block all possible workarounds to access a certain webserver but you may use a layered approach to make it very hard for the average end user to access said blocked content

  1. Allow/Block traffic based on destination port(e.g. only allow tcp/80, tcp/443, udp/53)
  2. Allow/Block traffic based on destination URL (e.g. block category PORN, Web-Proxy)
  3. Allow/Block traffic based on application (e.g. only permit http,https,dns)

A policy as stated above may be implemented by using a modern firewall that is capable of L7 firewalling (e.g. Cisco FirePower, Palo Alto Networks, Checkpoint, Sophos, etc. etc.)

I have only listed a few vendors for reference. There are many solutions for your problem and a firewall capable of deep packet inspection may be the best fit to solve your issue.
