I can confirm the fact that a lot of the time your account will get suspended. I raised a guys eBay limits a few days ago and they banned his account. When I called up on his behalf and asked what the reason for suspension was they told me that they consider FitBit BLAZES to be very high risk items and asked how I was able to sell at such a low price and who my supplier was.
Note: they only mentioned fitbit blaze as "high risk" - charge/hr/2 and surge are fine.
