When adding a Twitter profile as an URL to an artist page, it seems that
Danbooru automatically adds an ID-based counterpart for the profile:
For example: https://twitter.com/chinpokonyan
Becomes: https://twitter.com/intent/user?user_id=1019840024026570753
This is good, as it prevents losing the profiles, because Twitter names can
change and thus break the URL.
The problem
However, there’s one drawback in the intent/user?user_id=
URL format:
when opening these links, Twitter will always show an annoying “follow this user” dialog.
The suggestion
I think it would be better to use the following format instead:
https://twitter.com/i/user/1019840024026570753.
This will also redirect to the correct user profile, but without the follow nag.
