Min viewers raid and removable raid messages
I have recently seen a new mass raid bot appear in the wild in multiple channels within days of each other, with 2 variations of either many hundreds of users or just 1. The only current way to 'solve' the issue is set raids to Network (friends, followed etc) or None (block), this does not give enough control though.
Issues:
* Twitch posts a non-deleteable raid message
* No control over mininum number of viewers in a raid
As a moderator I have no way to help the broadcaster in a situation in which a raid bot appears.
Solutions:
* Implementing a minimum number of viewers in a raid, and have this configurable via chat commands.
* Provide the UI and IRC with the ability to delete the raid notifications. This would also solve when usernames contain phrases/words a broadcaster determines inappropriate. I've checked with my own moderation bot, and although an Id is provided with the raid user notice, if you attempt to call /delete {msg-id} the system returns a notice with a msg-id of 'baddeletemessage_error'
