Can I run MP on fresh accounts?

Since I don't have the time to age the accounts and can't find a suitable marketplace seller, I am about to make my accounts right now and run them on low settings for a few weeks. Do you guys think that would be safe to do? By the way, these accounts won't be spam accounts, they are brand-looking.

I wouldn't run them at all if they are fresh accounts, I would try and age them for a month or so before you put them on MP
