Well, if someone considers removing his/her own imagery after Mapillary acquisition, maybe you could at least consider transferring your imagery to OSC first?
There is a great transfer tool available, works like a charm, no need to leave your computer up and running, takes 5 minutes to set things up and all the rest will be done on the server side.
