Is 'Crypto Justice League' asking for a 'due diligence fee' another recovery scam after my crypto loss?

Okay, so I lost a significant amount of Bitcoin (like, low five figures) to a fake investment platform last year. I reported it to my local authorities here in the Netherlands, but honestly, didn't have much hope. Then, out of nowhere, I got an email from a company calling themselves 'Crypto Justice League'. They said they track crypto scams and have a high success rate. They even had some details about my original scam that seemed, well, believable. They're asking for a 'due diligence fee' upfront, about 0.5 BTC, to start their investigation and recovery process. They say it's for 'blockchain analysis and legal prep'. They claim they don't take a percentage of the recovered funds until it's actually in my account, which sounded good. But that upfront fee really makes me nervous. Is this a common thing for legitimate recovery services, or am I about to get scammed again? I really can't afford to lose more money. Does anyone have experience with 'Crypto Justice League' specifically, or these kinds of fees?
