You're wondering if you've ever considered adding an option to "Check Copyscape Before Submitting". Where could we enter our Copyscape API key and / or username / password (as needed) and GSA would check Copyscape before sending any articles.
Of course, this would be too resource intensive for mass mailing, but for network posting I (and I imagine others) would save a lot of time, because as it is now, I have to log in manually and check all my articles for copyscape after they have been published. This may be an option in the project settings, which is disabled by default: "Check Copyscape before posting" … and if the Copyscape check fails, the log would display "Failed Copyscape, Skip Post to Target".
I looked through the macro and coding instructions and saw no way to do that. Is there a possibility at the moment? If so, I do not mind modifying my network posting engines to add this variable in … but I could not find any information about it.
