The inescapable fact about Tor is that its traffic patterns make you stand out prominently. Just the fact you’re using it automatically makes you interesting and worthy of a closer look. All well and good if you’re just maintaining a cookie recipe site on the dark web, but it’s rarely ever that, is it?
if you're worried, you could use a popular VPN to connect to Tor - using a VPN is less interesting. also, P2P app developers could consider running non-exit nodes in their clients for popular apps. there shouldn't be legal risks unless you're running an exit node, and this adds more noise to the signal of Tor users.
