What happened to Ivana Alawi and Pia Wurtzbach?

I'm fairly new to reddit and esp to this sub. Nakakagulat lang na super problematic and hated on pala nila. I used to like them (not rlly super naman, naka follow lang sa socials + occasional na nagwawatch ng videos pero di tlg fan haha). How come dito lang sa reddit napag uusapan issues nila? Or perhaps I'm just not like checking the comments under their posts whatsoever?
