Re: Forum hacked?
There is a commercial alternative (Discourse) that Apple use for Swift language forums (this does seem to hide email addresses).
It looks pretty good.
I couldn't find out if it does indeed hide email addresses, but aside from that, it's free if you install it on your own server.
Good news! Discourse is, and will always be, 100% free and open source software. You may also want to self-host for reasons other than budget, including privacy or full control over the free software that you've installed. Here's how you can install it yourself on your own server.
