Just don’t hold a high hope that you are getting it back, just make a new one, it’s not like anyone is using Google+ for other reasons anyway. In that case, try contacting Google to help clear your account. This area includes Writing Lab hours, services, and contact information. The account has been blocked, and you probably wouldn’t be able to log-in again if you ever log-out. The Purdue Writing Lab Purdue University students, faculty, and staff at our West Lafayette, IN campus may access this area for information on the award-winning Purdue Writing Lab. It is now posting spam to random Youtube videos, usually offering a fake site that promises fortune but is just a scam to get your money. If the problem persists, your account itself could have been compromised. Do not entirely disable the “cookies third party” blocker, however, it will put your computer in security risk, from viruses and all.

Just make an “Exception” for both the two sites on your browser and it’s good to go. If your internet browser has the function to “Block third-party cookies” enabled, or if accepting third party “cookies” is disabled, then we will need to change that. Google+ is considered “third-party” to Youtube while Youtube sees Google+ as “third-party”. Youtube and Google+ are 2 different websites. Then why can’t you comment on Youtube? The source of this problem would be the “Cookies” on your internet browser. Fortunately, it’s not required anymore :) Anyway, since then, a Google+ account is required to comment on a Youtube video. Since November 2013, Youtube received a forced integration with Google+, something no one saw coming, something no one “appreciates”.
