You get a lot because:
1.The IP address you are on has shown problematic activity online recently in one of our data sources.
2. The site owner decided to block the country you are visiting from.
3. Your actions are triggering a Web Application Firewall rule that the website owner has turned on.
If you anonymously buy a non-free VPN subscription and connect to it from Tor, you should see reduced captchas. Running VPN > Tor is also good to hide the fact that you are using Tor.
