...Build as many articles as possible=check...
When this is checked, I have the same problem. Maybe this is too many information and needs stronger computer?
I find why the program stop scrapping (stop working) for a period. When I click "stop" on the scrapping process 2-3 times in the period of 30 minutes, the program can't scrap from both places (Google and Articles) for a hour or two. Now I wait to finish with the scraping instead hitting "stop" or "new" and haven't problems.
I want to share the first results with WAC. I use the created articles to sell backlinks on my private network. Just ~20 days ago the way I create articles was the follow:
- scrap few articles
- get random paragraphs and create 1 article adding image and random HTML tags
- spun this article and submit it
My aged private network (the domains are over 5 years old and I use it from about 2 years) with 13 PR blogs has taken 100-150 hits daily.
After ~20 days of using WAC the traffic to the my private network is tripled (400-500 hits/day). I am sure that the reason for traffic increasing is the new way of creating the articles, because on the last PR update almost every blog is with lower page rank, I haven't more sells than before, but my clients gets better SERP increasing. Today I can say, that articles created through WAC passed on goolge's penguin for at least 20 days (and panda maybe).
This is the stat for 3 sites with infolinks installed (I use it for tracking only):
