And money or not, if you collaborate with a fashion designer and post the result on Instagram, you're an Instagram model. Because you model. On Instagram. It can be a cool creative hobby.

I guess you're supposed to get a gut feeling for it in 2D/3D and therefore get some kind of intuitive understanding that it could work similarly in 3D/4D. Trying to visualize maths is though :/.

How does it work? Shaking?

I stop expecting being motivated for anything. I just do the things because they must be done. If I wait for motivation I don't do anything.

For which you actually model. This is quite literally modeling, on Instagram. And it's not only marketing, it's also art. If you accept fashion and photography as art. I see the time and effort that my gf (and everybody I know in the European alternative scene) puts in it, shoots planned six months in advance, made-to-measure apparel for the occasion. It's common in the Gothic, alternative and fetish scene. Everybody gets something out of it, even when there isn't any money involved.

There are many indi designers of clothing and accessories who heavily rely on Instagram exposure for their business. Those designs are shot on location with a photographer, assistant, makeup artist; people have to travel a few hundred kilometers to make the thing happen. This can be a surprising amount of work, and it's definitely not selfies.

What password? And what does swiping have to do with it? Password fields don't even allow swiping, and swiping doesn't guess strong passwords. I'm confused.

If you're not ready to provide for the humans you create, don't create humans.
