Here is something that I try on my V2K abusers. When they are attacking us with V2K they seem to always also be watching and/or listening. I find some good quotes from the Bible to read them, so they can hear the word of God. I will do this periodically throughout the day.
If the quotes you picked don't seem to be effective, you can try switching to some new ones and that might help. If you find some good ones that are effective on your operators, just keep using the same ones. Write them down if you have to. Anyone else know a good strategy?
