Yes I said when I joined this site, that I would never block anyone because I was always interested in alternate opinion. But I forgot that a lot of alternate opinion can be mindless and boring, and you can just have too much dross blocking the pages. I have therefore blocked someone at last, not for disagreement or quality but just because of quantity. (Probably the same person. )

You can also go to your settings on your profile. There is a tab for blocked profiles. You can add that person there, and see who else you have blocked. If/when they are no longer with Ag.com their profile will no longer be there. So if you have blocked someone and are wondering if they are still on Ag.com you can check there. I have about a dozen people blocked, I do it for my peace of mind.

Click on the person's profile. Scroll down. On the lower right is an option to "Block user." You can choose to block him/her for one day, one month, three months, six months or forever.

you can also go select their profile, scroll down and there is a Block user option on the right side.

Click the gear icon in the upper right. Then click the right-most tab and enter the name of the person you want blocked.
