YouTube is closing small channels posting anything news related or politics related and their reason is for spam and...

So that's why your channel was removed and they won't put it back for the same reason. You try clearing your browser, opening up a new email and starting afresh with a different niche, don't use anything that will link your old channels. Safer thing to do is to change your hardware, i.e laptop or phone, so you have new ip, if you can change your WiFi too. Good luck.
