Guest Board posting without spam swamping

[jilly]

I have a guest board that I use, for people to post on if they are having trouble registering, or want to ask questions before they register. It seems to be getting swamped with spam. But I don't want to give my mods too much work, having to delete all that spam, or if I make it moderated, then they'll be moderating those spam posts too, right? What's the best way of handling this?

Disallow posting of links. Use the spam management tool to reject links until 1 post.

You're actually better of using Tenants human anti-spam system, as that stops all the sneaky types getting through too, which XF will not stop.

I use that and allow guest posting on all public forums without any issue of spam. They try, sure, but they're banned and rejected automatically without mods seeing anything.
