There could be many reasons for the red flag which is why we individually review all support tickets regarding red flags. If you haven't already, you will receive exact info why you were red flagged. It is different for every user so I can't speak for every red flag.
When you are red flagged, it means we must verify your traffic source in order to know you are not in violation of our ToS. A red flag does not mean you are in violation of our ToS but we suspect a possible violation. Common reasons for red flags include: too many blank referrers (90% or higher of total traffic volume is a good estimate), poor quality traffic, or suspect activity.
The review process (via support ticket) can take some time. Usually it takes 24-72 hours but some must be further investigated (very few users fall in this category) or if that user does not respond with the correct evidence/proof it could take up to the full 1-2 weeks.
If you:
- Send a lot of blank referrers
- Have very low quality, spammy traffic
- Doing something shady
You are likely to be red flagged. A great way to know in advance would be to contact the admin (via support ticket) and ask about your traffic quality to see if you will be red flagged (much sooner than payment date). This is the best option right now to know quickly since we don't have the resources to audit accounts every day or even every week (there are many thousands of users sending traffic at any given time).
In the short future, we'll be implementing some features to quickly audit and red flag accounts within 72 hours. This will save some headache for our users and cut down the time it takes to review these red flags.
