Pinterest really has a spam problem. Although Pinterest attempts to get rid of spammers, they have a huge battle to look forward too. Spammers using Pinterest create dozens upon dozens of fake accounts for that specific purpose. Yes, you can report the Pins and etc and see if something is done about it. In the meantime, your Gmail account still gets loaded by anything you followed. Keep in mind, there are buyers of email addresses that target Pinterest too.
- Install Block Sender for Gmail by clicking the “Install” button found in the upper right-hand corner of this site. The installation won’t take long. Open Gmail when it is done.
- After signing up for a Block Sender account and linking your Gmail account to Block Sender, open the unwanted email from Pinterest, and click the "Block" button on the messages toolbar.
- Select the "Emails from this sender" option.
Once this is done, you will no longer receive emails from that Pinterest email account. If you ever decide you want to start receiving their emails again you can simply unblock the email.
