I get why people are skeptical, especially with so many scammy ""recovery"" services out there, and it's hard to trust anyone after being scammed. But not all recovery services work the way you're imagining. Some, like the legit ones, don't hack accounts. If needed, they rely on tracing transactions, protective measures, and even legal strategies. I had a friend who recovered some stolen Ethereum through a white recovery service, so it does happen, though it's rare and depends on timing and circumstances.
Any recovery service who claims to hack the scammer back and get your money back is 100% scammer. I know a some good services they are not recovery services, they call themselves Crypto rescue services. what they do is if you are about to receive a payment in your hacked wallets (lets say your hacked wallet is eligible for an airdrop) what these rescue service can do is that they can help you withdraw your tokens before scammer. they use scripts so they can withdraw tokens faster then the scammers. that is the only thing a rescuer can do for you. there is no way to bring your money back that are already stolen by hackers.
