By following the page linked in the 404 message it seems they closed the ability to follow permanently, if so the follow method should not be documented anymore.

Hello! Thanks for the issue. If this is a general help question, for a faster response consider joining the official Discord Server

Else if you have an issue with the library please wait for someone to help you here.

We do not remove methods in accordance with twitch changes, as this would put the breaking change on the lib instead of the api. There is no action needed here.

[Gouvernathor]

Well you could remove it from the documentation at least, since it doesn't do anything now.

I'll simply add a warning to the docs for now. This is obviously removed in 3.x
