Your Singapore traffic is most likely one rented network
At the end of August, Singapore became the second country by pageviews on one of our sites. No conversions, no interaction, an average session under ten seconds. We took it apart down to the network level, and the whole spike turned out to be one farm renting Tencent address space. Blocking the country is the wrong fix. It shuts out real visitors too. The country is only a guess made by a geo database. The next update may file the same addresses under another country. The datacenter behind them stays the same.
