Consider Tor. Each circuit involves three relays aka ORs aka nodes: entry guard, middle relay and exit relay. An adversary could deanonymize a user by combining information obtained from the three relays used by one of their circuits to some honeypot.

One cannot trust any particular Tor relay to refrain from logging and cooperating with adversaries. However, the Tor design mitigates those risks by using three relays in a chain. An adversary would need logs from all three relays in a circuit.

One can also use nested chains of VPN services. That's far less anonymous than Tor, for many reasons. Tor creates circuits more-or-less randomly, and by default they change at ten-minute intervals. VPN chains, conversely, are typically static. But the bandwidth is much greater.

And then one can use Tor via VPN chains, and route VPNs through Tor. Also, although routing Tor through Tor doesn't work well or do much good, one can proxy through remote desktops on VPS. Latency sucks, but you get used to it.
