This may sound stupid, but from my perspective renting random VMs on vast.ai is safe in general and might be safer than using traditional cloud providers in particular. Consider this: on your VM a new image starts several times a day, each time with a new volume. It downloads tens of GBs of data and weights for training. Once training is done, everything gets cleaned up and the process starts again for a new tenant. This constant cycle makes it kind of difficult to track and extract any meaningful data from it.
