uzairsyedahmed You mean according to your own site guidelines? If so, no, Akismet detects spam according to its own methods (I'm not sure if they are published or explained anywhere) and is completely automatic.
I would add that personally after using Akismet I would recommend you to use Spam prevention from Blomstra (https://discuss.flarum.org/d/31524-spam-prevention), it requires a bit of configuration if you want to customize some things but the result is much more reliable.
