Suggestion: Publish two lists - verified meetups, and unverified scraped meetups

[joeytwiddle]

Just a thought, since we use heuristics to scrape the Meetup events, and sometimes they go wrong, we could actually publish two lists:

1. A list of verified meetup groups (e.g. from an allowlist), which should satisfy most users.

2. A list of meetup groups which we found using heuristics (minus the first group). This additional list could be used by more adventurous users, and also by maintainers.

Perhaps on the website, we could give a green tick to the verified meetups, and an option to hide/show the unverified ones.

On the calendar app, if the two lists are imported with different colours, then a moderator can see at a glance when a good group is in the second list, and take some action to move it into the allowlist.

Disadvantage: Current code would need to be updated to acknowledge which category a particular meetup should sit it.

Challenge: Do many people really use the calendar feature?
