I found that a streamer I watched the followage command was broken so I decided to make one that works. The streamer has to login as it seems its no longer a public api on twitch to get followers.
Anyways the site is: https://commands.garretcharp.com
You need to login and then you can add the command:
$(urlfetch https://commands.garretcharp.com/twitch/followage/$(channel)/$(touser))
Format (any values that are 0 would be omitted):
@viewer has been following @streamer for x years, x months, x days, x hours, x minutes, x seconds
