Hot to block particular e-mail address?

Can I block an email address on Google+?

• I'd like to block a specific email address on Google+, so that if they ever create an account there, they shouldn't be able to find me. Right now, this email address does not have a Google+ account. Facebook does have a way to block email addresses, even before an account is connected to them. Does Google+ have such an option?

• Answer:

  Sometimes you may get unwanted mail that isn't necessarily spam. While you can't currently block messages from specific addresses or domains, you can set up a filter to send those unwanted messages directly to Trash. To set up a filter, follow these steps: Click Create a filter under the search box at the top of any Gmail page. Fill in the appropriate fields with the filter's criteria, and click Next Step. Choose the action you'd like for these messages by checking the appropriate box. (In this case, we suggest checking Delete it.) Click Create Filter.
