It´s a yeah-bot. It automatically yeahs posts in communities c: But some also try to do it by hand So no, that´s not generous, but trying to get followers. There are some who try that to make people happy, but a lot of them just want follows... I´m sometimes going over the posts in the YT-community and try to find things to yeah or comment (found a lot of nice people) and you see the yeahbots
