Some questions about asset bundle

We are currently using cocos creator version 2.4.11.
Since the current apk is large, we want to split some resources and animations to remote, and then prompt users to download.
The official implementation is through asset bundle, but some posts say that turning on asset bundle may lead to the risk of banning Google Play and AppStroe games, or even banning developer accounts.
So I have two questions:

  1. Using asset bundle lead to the ban of developer accounts
  2. If there is such a risk, what method should we use to implement the function of remotely downloading resources

Anyone wanna take a shot at this question?
