FAST posting articles to WP with less CPU capacity. Is it possible?

Good day guys..
I have private network of 100 WP blogs. They all is on seo hosting with 50 unique C-class IP adresses...
The problem is that I'm using article marketing robot for posting my spin articles...And even 5 threads is too much for this type of hosting (hosting administrator just ban IP if there are more then 1 thread posting articles...).

So I am interesting in FAST method of posting with less CPU capacity to the hosting...

Any ideas? What can u advise?

It will be good if I can at first make all tasks (in example prepare 20 articles in my admin panel) and then just post to all 20 articles in 1 thread to WP (and get all 20 livelinks immediately) ...Does such software exist?
Thanks

Could you send me by PVT exactly what you want... i'm working on a similar plugin and i'm interested to learn about your suggestion.

Thanks
