[FEATURE REQUEST] Auto-moderating #showcase

[WhiteBlackGoose]

From my experience, more than half posts on #showcase don't follow the format, and because I'm an active user there, I want to suggest Modix to moderate it. Here is what, in my imagination, it should do:

1. Should check if there's a substring 'License'
2. Should check if the post contains 'Source' or (github|gitlab)\.com\/[A-z0-9\-\_]\/[A-z0-9\-\_]

If the post does not follow those ^ rules,

1. The post gets automatically removed
2. The user gets pinged in #bot-spam with "@User, your post was removed from #showcase: {their post}. We suspect it does not follow the format: {format}. If you think it does, react with :thumbs_down:"
3. Now, if Modix wasn't right and the user did follow the format, the user can react with "thumbs_down" emoji, and the post will be recovered.

Note that the concrete details might be changed, but I'm suggesting the overall idea. It's not like it helps 100500 members, but at least it helps those who actively visit #showcase and #project-talk (and as a result, often have to ping posters and tell them that they can't into format)

I'd be down for this. Generically, I'd call it a "template channel" or "validated channel" feature, where all incoming messages must pass a configured validation. Validation could simply be a single Regex pattern, or a more sophisticated collection of rules. Channels and rules are configured via webapp.
