Well I was testing my code to subscribe to different users using the webhook, but then in my database I noticed two instance where two user names were assigned to the same user ID.
Here they are:
user_id: 139181164 contained 2 user_names:
nzurisana (https://www.twitch.tv/nzurisana says “Unless you’ve got a time machine, that content is unavailable”)
sana (https://www.twitch.tv/sana says “User Offline”)
Second example is
user_id: 237700531 contained 2 user_names
chayla_l (https://www.twitch.tv/chayla_l says “Unless you’ve got a time machine, that content is unavailable”)
colossalcake4 (https://www.twitch.tv/colossalcake4 says “User Offline”)
Am I to assume the “Unless you’ve got a time machine” user_names are old user_names that are dead and gone?
