Trying out the service with my old Bitcoin address, and it works. But the listed address was posted in 2016, there is an earlier time I posted that address on this forum(2014). Does that mean you only scrap data on some specific year or section first? Or it's just the scraping process that still not yet completed?

I might be wrong but aren't there a service about address linker with BtcTalk username already exists? I can't remember the name but somehow I remember.
