Moderated membership for community?

Would everyone be OK if I switched this community to moderated membership? The main reason I ask is that we've been getting a lot of posts from Russian spammers here lately, and it's getting tiring to delete their posts.

Edit: For right now, I've set community membership to moderated. I may disable this at some point in the future, but I'm pretty good about checking my e-mail from my phone. I've also added a note describing the situation to the community profile.
