After working for some time with youtube + ppd/cpa I have been testing some things about mass ban. I'd like to share my experience about things you should avoid doing if you do not want to get slapped by youtube. I have noticed that there are 2 types of bans. A massive ban and a TOS ban. TOS ban is simple - it occurs when someone flags your video then it gets taken down while you receive a strike. It is popular belief that you get 1 strike per 1 video.I tested this thing myself - I uploaded 10 p0rn videos.Flagged 4 of them and after about 5 minutes they were all taken down giving me ONLY 1 community guidelines strike.After that I flagged another 3 videos.Again all 3 of them were removed by giving me only 1 strike and when I flagged remaining ones I only then got my account suspended.I think same goes for other types of videos.I HAVEN'T TESTED THAT YET. MASS ban - when chain of accounts gets banned at the exact same time. First time I got mass ban I noticed that videos accounts which were created in long period from one another weren't banned.One was created february 21 and the next one only at mid-march.So it gives us about 3 weeks+ . Also my old yt account ( about 6 years old) was not banned either.Other accounts were wiped out even though half of them had nothing to do with violating TOS,I haven't boosted them or anything like that.Only bad thing about them is that they were created in short period ( 24h>). Second time I got mass ban I was smart enough to use shared VPN's to test if mobile phone number gets account chained - related to one another like creating all from same ip.I was right this time because all of my accounts were banned at exact same time even though I created every account with different ip.I wanted to trigger the chain reaction, I knew that shared VPN's weren't the best place to create accounts since there are a lot of people who also use same FREE ip's and everyone of them was packed with accounts.So now I know that even a simple phone number gets all your accounts chained.It's like barrel full of gasoline.It only takes 1 little match to f**k things up. I tried to create 1 account per week from my original IP and I haven't gotten a mass ban since.I was using same phone number for all of them.3 weeks had passed - 4 accounts created.I think this time I might be right about my mass ban theory. Although you won't get mass banned if you create low amount of accounts in short period and won't boost them.It takes something to trigger the mass ban.For example - you create 2 accounts, keep active on them, don't boost anything and keep things natural. Different story with mass account creating. Lets say you create 10 accounts in same day - upload videos only to 1 account and keep other 9 untouched. If you boost videos early in that one account you will trigger the effect.I mean you might not get banned the same day or week, but when the mass ban occurs it wipes all of 10 accounts even though 9 of them had nothing to do with violating toss. The more videos you will boost the faster you will get banned.It is question of time once its triggered. :bs2: I tested things myself.I created 20 accounts in 1 week period 15 of them had videos in them and other 5 hadn't.All from same IP.They were untouched.Boosted video early - mass ban was triggered, but only after 1 week.All of the accounts were wiped - the ones with videos and the ones without videos --ALL OF THEM-- Things that trigger mass ban - early boosting,mass account creation,previously banned and re uploaded videos with same md5 <--- Strangely enough TOS ban does not mix into the stew lane: I don't want to ruin business for youtube account sellers, but that's what I found out. Most of you will probably call bullshit.It is just what I was testing.This is where mass ban coming from.You need more than one ingredient to trigger the mighty mass ban, not only naked girl in the video This information might be valuable for some people.Don't take my word for it.Test things yourself. Create 2 accounts from one IP ( make sure you get the chain linked).1 with and 1 without the videos.Boost videos early,copy them others (make sure that same video was banned from youtube). The more ingridients you put into the stew the faster you will get mass ban.Just make sure that at least 1 account is completely untouched and you will see what I mean. It might look like I am some kind of mad scientist, but these tests will help a lot of people.
