What..? It's not letting me see my ID

You can get your user id a number of ways. You can use the API and get a user id like so: https://api.scratch.mit.edu/users/–irrelevant <— replacing this username with any username, your user id is 123418488.

Or you can right click any user's profile picture, click “open image in new tab” and the underlined part of the link will be your user id: https://uploads.scratch.mit.edu/ge_image/user/123418488_90x90.png

Alternatively, you can use inspect element or copy link address on the image to get the link above.

Does this post help: https://scratch.mit.edu/discuss/post/6021293/ ?

Only partially, because it tells you how you can use the user id, but not where, as using a user id like this: https://scratch.mit.edu/users/123418488 does not work.
