100 isn't much at all, so there's not much risk in not using a proxy. Is there any particular reason you don't want to use a proxy?
I harvestd about 100 autoapproved blogs, only high pr and do follow blogs, i want to submit it without the use of proxiesm can be dangerous for me not hiding behind proxies?
Why risk? Just buy private proxies. You'll still have a high success rate!
