How can I block individual members?

I use the same forum system as Ring on a major cellphone manufacturer as a moderator. The members have the ability to block other members. I've found many on here that just spam threads to get attention or act uncivilized. Is there a way to do this or could it be turned on? I report these people but some disappear and some are still here. I know you are relatively new with the member to member support system. I've been doing it for 10 years now. On the forum I'm a part of we do things a bit differently. We do not remove any posts at all unless they are spam or just wrong... We edit posts as needed. And of course we give timeouts or bans once the forum managers gets involved. The other thing I noticed is that whenever a post is moved or merged I get a email saying that. That's something that I guess we have turned off since i don't see it and no one else in the community does as well. Thanks for hearing me out. Hopefully there is a way to block others so I don't have to see their posts it replies.
