About year ago problem was much bigger, horde of fake users and it worked: a lot of low quality rooms was on the all first places.
Right now situation is much better, because CB added some anti bot algorithms. A lot bots still exist but it does not promote low quality rooms - good and average only.
Most of old botnets was owned by Romania/exUSSR owners (I know it because it was advertised on many Russian speaking webmaster forums). Current botnets owned by Spanish webmasters (as I think, because almost all promoted rooms are from the Spain). This new botnet is unseen by antibot or these rooms exist in antibot whitelist. About white and black list of anti bot read below. I don't want to be rude, but
@Mila_ also promoted by this bot net. I don't know she knows about it or not (I think not, maybe bot net uses some rooms for "washing" the fake members). For her situation is good, for the others it does not. This situation is bad for almost all models from the first page, because of unfair market and because position and tips don't depend of what they do on cam.
About white and black lists.
White list.
Some rooms exist in white list - room can have a lot of guests and member right after from the start (2-3K right after start and 200-300 registered used in 1-5 minutes). And these rooms don't receive any penalties. But if someone want to try doing this: I don't recommend - you will be in black list instantly.
Black list or black mark (I don't know how to correct call it).
If some model received a lot of fake users it receives a black mark (I think black marks have a different levels). After receiving this model can not receive more users than specified amount. And this amount depends on online time. Some example: on 30 minutes not more than 500 users, on 1 hour not more than 1000 users, on 2 hours 2000, etc. Because a different type of black marks are exist, each model may have a different limits. Also I think rooms with the new tag in white list by default.
How it works and how to see that some black mark are exist:
Usually online grows slowly and drop only on disconnects or cb lags. But when limits are enabled - online slow up and quickly drops to some level. As example users can slow up from 1500 to 1700 in 5 minutes and drops down in one second to 1500, after that slow up to 1750 in 5 minutes and drop down in one second to 1550 and again and again.
I don't know algorithm, how it choose what member to disconnect from the room, but if room full of club members - they reconnect to the room too often.
Some one can think - yes this is good. But everybody can give a black mark to any room - just put a lot of stupid bots detected by antibot system like a bots to this room. And this used now too often for room denote on the main page.
And yes this is 100% true. I helped a few models with OBS setup and with some tech consultations and they asks me if they have some problems. They have the same situation: one day they receive a lot of guests (500-1500 viewers) in the first 5-10 minutes for 10-40 minutes and after that these viewers a gone. And on the next day they receive a black mark (dropping members counter in one second each few minutes). And girls are too scared to write to cb support because of tons of bans in the 2018 year.
So situation at CB right now that the someone can do anything (I don't know - they have some close relations with cb tech support, or just find some bug in the system). But everybody else depends on bad will some 3-d party agencies.
P.S. I didn't want to wrote about black marks, because it can be dangerous for everyone. But right now this is used on regular basis for denote popular rooms.
P.P.S. Sorry for my English and some errors if it exists, it does not my primary language. I've tried to write understandable
