Some of the advice here is good!
Heres what I suggest...
1. Dont use any of your browsers but use a portable version of FireFox

2. Get a Free SIM Card and make brand new Accounts manually, upload pictures, profile information etc. MAKE SURE TO USE A DIFFERENT I.P TO THE ONES THAT GOT BANNED BEFORE.
3. DO NOT UPLOAD ANY VIDEOS STRAIGHT AWAY, do some random activities such as subscribing, commenting etc make sure they are all on unrelated videos!
4. Create a GMail Account and send messages to your other e-mail accounts (not associated with Google i.e Hotmail/Yahoo etc) Just start some random conversations
5. After waiting about 1-2 Weeks THEN upload a Video, make sure their are no links or anything spammy in the Videos. Keep it 100% Whitehat, no boasting views, likes etc
6. After about another 1-2 Weeks you can upload Videos with links etc but dont upload too many videos or too many per Account in a short amount of time
7. Observe your results and tweak things accordingly!
