This is a server that allegedly has some BTC on it (AFAICT it’s just a claim made by the website itself, zero corroborating evidence), definitely nothing else valuable, and likely has a lot of monitoring to capture whatever exploit you send, and with a less-vulnerable-than-usual setup. Unless you’re really desperate for the money and want to take a gamble on the server having the not very meaningful bounty it says it has, it’s strictly negative value compared to the average production php server that’s still unpatched. If I have a working exploit I’m mass deploying against everyone, I too would skip this one, similar to how mass market malware tends to disarm itself when it detects security research tooling.

No, I don’t think actual working exploit is trivial either, but people are wayyyy overselling this stunt in this thread.
