Am I the only one who noticed the number of spam comments is too high?

I noticed this trend that the number of spam accounts and the number of comments left by these bots? is increasing. Just take a look at this thread here:

Or this:
https://managewp.org/articles/17522/gdpr-compliant-form-builder-for-wordpress#comments-section

Or this:
https://managewp.org/articles/17250/preparing-your-wordpress-site-for-google-s-upcoming-mobile-first-index

Any ideas or solution?
