Changing proxy for existing youtube accounts

I had logged in to four youtube accounts with one proxy, but then I noticed that I couldn't upload any videos with that proxy so if I will use another proxy for those youtube accounts I will get them banned or not? I had logged in only a twice.

No you won't get banned but chances are the new proxy won't let you upload videos either. Give it a try and see

OP your youtube account may get banned

From now try using the youtube accounts from different proxies regularly

Thanks
