I know some guys who've met dozens of girls using it.
It still has a large number of users though: I checked on 15 December 2016 at 7pm and there were 522 women online in Jakarta (vs 537 on Indonesian Cupid). Badoo attracts 99,9% of Indonesian girls, from all background.
For this reason, this is where you will meet the most girls who can speak English and who have well-paid jobs.
This is also where the most girls are interested in meeting foreigners.
Most of the information on the review is still valid, but it certainly needs an update on the world of online dating through websites or social apps such as Badoo, Indonesian Cupid, Tinder, We Chat, Skout, Beetalk, etc.
If you are looking for a great girl in Jakarta, online dating is by far your best chance.
