Looks like the article was deleted and purged from archive.org. I wonder if anyone saved a copy elsewhere?
From the comments it seems likely the author realized they may have accidentally committed a crime or at least done something that could cause real legal consequences for them and quickly destroyed the evidence. That's probably better than leaving it up but I'd wager it wouldn't protect them from any legal consequences publishing the article already made possible.
According to Twitter they removed it due to a legal notice from Dotpe, author still seems to believe he was just accessing public data unfortunately which does not look good for him should Dotpe choose to take it further
