not sure if there is a correlation or not, but blasting your profile baklinks, will most likely make some of them indexed, hence get picked up for DA calculation.
what you need to figure out is the DA for your profile backlinks and see what they end up being after your blast. would be an interesting case study.
i have blasted my profile backlinks, but not directly. i have created URL shortners for my profiles, and then I blasted those URL shortners. can I say if this has had a positive impact on my serp, not really, but did not hurt me.
