I disagree, given I work on big channels.
This is what I would do and I do, do, with a big channel. That said most of the big channels I work with, don’t do anything with follower checks anyway.
But I do use the follower webhook to update certain things internally. And periodically pull the whole list, rarely.
Then check when you need to. What’s your use case for needing the follower status?
Side point: a fair few “big channels” have their chat in follower only mode, so if they can talk in chat then they are a follower.
Correct.
Webhooks are pushed from the server, to a web accessible client. Need to get around that, use a tunnel like NGROK. Or just put your follower handling on a webserver, since you are gonna be processing a lot of data and might need the grunt of a bigger box.
