Booths actually allow for this in the licenses usually, which is why it's fine. I myself can't do anime drawing (of which imo is the true bulk of the work for booths requiring 2d drawing anime skills) but in my work I used 3 different base models loaded up in the project as reference, it lines up with none of them and after I had general form I spent a lot of time getting it how I liked.

This type of stuff can be super grey area.

Rindo itself is probably an edit of another booth, and booths technically have origination in vroids usually and so vroid -> booth -> other booth is kinda the meta

The issue with tda is people make complete fucking garbage out of it and make the OG author look terrible and it violates the license of the model. Booths allow derivative works so you can sell clothes and shit so a derivative base body is probably free game too
