Act as if your account is always under review.
Make absolutely certain you don’t unknown infractions (or areas where you aren’t paying attention) jeopardize your account.
MOST of the time, suspensions come from things you could know about RIGHT NOW if you are paying attention and know where to look.
Let’s use a health checkup analogy: You are obese. The Doctor told you you will almost certainly get high blood pressure and diabetes unless you do something immediately to correct course. So, they give you time to think it over. After a real reality check and some contemplation you decide you are getting a gastric band. They provided some options for you to choose from in advance but they don’t actually care if you get the gastric band…just as long as you do something and do it now. What might actually be best for you is NOT the gastric band. You simply have to change something, cut something out, not eat as much, get exercise, etc.
My point is–right now, while your account is not suspended, you have a choice in what methods you take to keep your account healthy. It is just as dire as the health situation and you must do SOMETHING(s). You can’t just sell a lot and have good feedback. That isn’t enough. Perhaps you have some inventory you should never sell again. You should recall it immediately and remove it from your catalog. That means immediately, as in TODAY. Perhaps you had too many instances of buyers saying something was not as described or used sold as new, etc. Whatever caused those, you need to remedy immediately. And, you need to be VERY proactive (weekly or daily) looking at some specific reports to find those issues before they pop up again.
Be very proactive with every Performance Notification and with every AtoZ claim and with Buyer Messages and request for refunds or returns. You have to open cases to reply to those Performance Notifications so they don’t come back to bite you. You also have to follow up on every single ASIN change notification to make sure your product still matches the product detail page.
You have to make sure you have invoices to back up every purchase. Assume that you are going to get claims where the buyer says the item you sold wasn’t new or that it was counterfeit. Every single receipt or invoice for every single item you sell should prove that the item sold was new and genuine.
That’s a brief overview of specific and regular steps you should be taking.
