Whenever I visit my site’s dashboard, the first thing I see is the bold red Spam count.
Instead of wasting time deleting spam comments, I prefer to let Akismet do that automatically, so I don’t need to see how many spam comments there are.
This little plugin simply hides that part.

Hide Spam Count

Hide the annoying spam count from the Dashboard.

Per Søderlind

Based on a users IP address, WP-DenyHost will block a spammer if he already has been tagged as a spammer. Use it together with the Akismet plugin. Akismet tags the spammer, and WP-DenyHost prevents him from accessing you site.
If you have a <a href="https://www.cloudflare.com" rel="nofollow ugc">CloudFlare</a> account, the plugin can add spamers to <a href="https://www.cloudflare.com/threat-control" rel="nofollow ugc">CloudFlare Block list</a>

WP-DenyHost

WP-DenyHost denies a spammer from accessing your WordPress site. WP-DenyHost can add spammers to the CloudFlare Block list
