Deleting users from the OJS database

Dear Asmecher,
we have thousands of spam accounts. I cannot merge one by one.
Would you please let me know how can I delete all the unrolled and/or spam accounts from our system?
We have OJS 3.0.0

I’ve read in How do I remove users for good? - #3 by sienp2016 that exists a command to delete/merge a group of authors. It could be useful. Which command is it?

And finally, how can I insert a captcha or recaptcha anti-spam in our register process?

Thank you so much.
Best,
