We don’t see a lot of spam, but we do get a fair few spammers (over 80 so far)

The reason you rarely see spam because the forum protections are quite robust, and you almost never see it. I don’t even need to rush to mark the account as a spammer either. This forum with the right add-ons and configurastion is remarkably good at keeping spam invisible.
