Tor traffic is for some ppl a no go. Better obfuscate it with bridges or use a VPN then.
Think of this: You’re hosting a darknet market and there’s lots of traffic going on your site. That Tor traffic can be used to find your server, which uses Tor connections and has a lot of Tor traffic. Oh w8 thats bad. With a VPN you can hide that lots of Tor traffic is coming from your server.
