How to Stop Spam Comments on WordPress Blog Posts

.
Hi, thank you for the great info even though I don't use WordPress! However for my question is if you disallow for comments to be made on your new posts, won't that lesson your ranking in the searches for your topic?

And by turning off the "allow for comments," . . . doesn't that mean no one can comment, . . . which is very important?

Therefore, that being the reason that it will not be found or Help with your views?

Best content, thank you
