XF 1.5 Preventing spammers from posting links


As far as I can see, spam controls only relate to registration? I can't find anything that checks the posts for links before they are posted? I can't find a way to limit a usergroup's ability to post links either?

So essentially, if a spammer gets past the registration barriers and sneaks in, he/she must be spotted by a human and a moderator needs to clean the spam up manually by using Spam Cleaner?

Or am I missing out on something?
