Please do not recommend wallet.explorer. They record users' IP addresses and provide them to third parties and blockchain analysis companies. The data they provide is inaccurate, so this service is bad for privacy and should not be relied upon.
Then please recommend me the alternatives that people can see a connection between an address and another just like the quoted post below.
I disagree if they provide inaccurate data, many people use this explorer to caught cheaters. However, you can show me where's the inaccurate data they provided and compare it with the accurate data.
It's true this explorer is bad for privacy, but as long as you didn't use it to track your address, I don't think it will raise a problem.
