CoD multiplayer

for past few days i've been trying to find any lobby for CoD4 and nothing. I've read that lobbies are still going strong but lobby searching mechanism is broken. How i can find any lobby?

In CoD:WaW i can find lobbies without problem, but not many players - around 110-120 players online.

Is any CoD multiplayer still going strong in 2025 and is playable without hackers?
