That seems too late for both of those, heh. :) I started on LJ in 2001 and quit in 2006. Orkut I think I signed up for in 2004, and only lasted maybe a year there. I seem to remember the Brazilian influence even as early as that.

LJ was huge in the Russian speaking segment of the internet well into the 2010s. Me and my friends started using it around 2007 and I didn't interact with English content on there at all.

The Orkut timeline I might be misremembering but I'm fairly sure I was already at the university back then which would put it 2006 at the earliest.
