Nah. He's not addicted. He's just booored.
I also don't get this attitude with people who think administrators really care about a single individual person. Everyone is just a number, and you're one out of thousands. When I ban someone on one of my sites, I just enter a name, click a ban button, and spend my other 23.9 hours of the day doing something else. People always fall through the cracks, and some get marginalized, but we are aware of this, and it's a non-issue.
The people who make spam filters are well aware that some get through, but all that matters is that enough don't get through.
