I would like

Hi, I would like to know which plugin under WPMUDEV allows me to block user IPs of those that are posting spam on my site. This is not for comments but for custom Posts that are done by registered users. Instead of blocking or banning a username, I want to block the IP so that the same IP cannot create an account on the site again.

My site is not a multi-site, it is an individual site where it allows people to post Job Ads for free.

Pls advise.

Thanks
