There has been a very large active block of mostly Facebook/Meta support numbers here for several months.
They alternate between dozens of numbers in this range daily which spans the entire 100 number block
One of them has a Facebook profile under the name Tushar Sharma in Bangalore, offering fake credit card payment portals, pay per click calling (ppc) and all sorts of scam related shit.
These are the active ones today
