What is wrong with men on tiktok on those (asian) girl livestreams?? (simps)

Hi, since like 3 months I'm on tiktok and since a few weeks I'm on the asian side of tiktok somehow. So all the time i get asian streamers suggested. Mostly from China and Korea. They all have like 1k to 10k followers and have like 3 to 100 viewers.
They are all around 20 to 25 years old. They either do it as full time job, or part time job while studying. It's theyr job! They are not there fun fun or make friends. They don't even stream from home, they all work for an agency. The agency have a whole building with rooms for streamers like that, that's why the rooms almost look identical. They even start streaming at 3 o'clock in the morning on the weekend theyr time, to get more gifts from europe and america, So every weekend they destroy theyr whole sleep schedule for money/gifts 😂
There are "obviously" only men in those livestreams. From 20 year olds to 60 year old creeps everything...

And now the fun part: Whenever there are level 0 people in theyr livestream, they are mostly bored and just playing games on theyr second phone... But whenever a like level 20 viewer joins, they jump up from theyr seat and ALWAYS immediately start a match/battle against another girl which works in the agency, probably even the same building. And then those high level members ALWAYS start sending immediately gifts. And the battles continues as long as the high level guys are in the livestream. can be 1 match, 3, 5 whatever. But as soon as they leave, the matches stops until the next high level person joins...

So my question now is, who are those men? Are they all *bleep*? Do they not notice this? I still don't even understand the point of those matches. The streamer just screams 5 minutes in the camera; send me gifts, and then lonely poor little simp men will send money?
Imagine going to work, to spend your whole income to a random girl on tiktok, just because she might follow you back and she writes you a "hi" here and there.
