I've encountered this issue some times in the past, too.
Sara took a note on what is causing a system generated moderation request for discussions here:
I assume your use of 'payroll' has caused your post to need approval (I remember vaguely a lot of spam postings here with excessive use of this word)...
Thanks for your post Rob,
We do have 2 things going on here:
1) Additional terms added to spam filter as indicated by Swehl above such as 'free, payroll, juicy couture' etc. due to the spammers earlier this year.
2) Glitch or 'Bug' which drives some documents, discussions to moderation.
We are working on a platform version upgrade which will help address the bug, but the spam filter terms will remain constant.
In terms of allowing members who are top contributors exception to the moderation process- the system doesn't work that way. LOL I even see some of my own stuff go into moderation and then have to approve it- such as QlikViews and Ideas. The settings are set by content type and community area not user.
Hope this helps and will keep you posted on any updates. I really appreciate your feedback on all aspects of QlikCommunity.
Have a great day!
