I had similar situation on WooCommerce shop. But it was much more signups per hour. Putting turnstile in front fixed problem.

My conclusion is to move from WordPress software as fast as possible, every WordPress site I manage gets bombarded by bots.

Hell every non wordpress software I manage also gets bombarded by wordpress bots.(not really, I am stretching the term to refer to wordpress attack attempts for dramatic purpose. But that still ends up being about 99% of my personal site traffic)
