It's very complicated.
If the model had just about any custom work done to it, or it was a commission, then it's bad and you shouldn't do it.
If it's just a reupload of a model that's either completely public, or is technically "public" but is under extremely tight lock and key (or no longer available), I think it's fine.
There was this really cute Pramanix MMD model a while back, but the chinks hoarded the model and put it up on a site specifically meant to keep out the "foreigners". I felt absolutely ZERO shame ripping that model from a public avatar, fuck those people.
Overall I would say it's bad, but I will make exceptions for things like models that are literally no longer available (such as timed sales), or models that have some gay password behind them.
