The documentation comment for BanIpManager::__construct() says it constructs the BanSubscriber

On BanIpManager::__construct() the constructor is described as:

Construct the BanSubscriber.

The first word should be a verb using the third person singular, and the class name is wrong (BanSubscriber instead of BanIpManager).

Using a similar description used, for example, for BookManager::__construct(), the description should be the following one.

Constructs a BanIpManager object.
