WordPress used to be an ordinary content management system, which was used by small-sized blogs and websites only. But it expanded into a multi-user platform, and all types of sites are now developed with WordPress. With time, the number of spammers targeting the WordPress registration form has increased. They intend to create bots and fake accounts that could spam your links and always attempt to inject the malicious scripts into your sites.
