A hacker every 3 hours posts lengthy diatribes in Polish creating tags for it.
He has somehow created "wormgive" as a username with a password and created a category to which he puts his diatribes and blog in my website that lacks the word "delete" as do other categories, etc. with the "edit/quick edit/view" alternatives.
I have changed my email and username passwords, and his username passwords, but he keeps returning.
How do I block and get rid of that hacker?
My site is elmelechvoed.com and elmelechvoednation.com
