I would start by giving them a warning. You have a viable reason to block them - clogging up comments. After that, if that proves ineffective, start blocking them, but slowly increasing their block as time goes on if they don't listen. Start with a 3 day ban and if that doesn't work, followed by a 2 week ban, etc. Because what they're doing is while obnoxious, not something you should immediately permaban for. However this doesn't mean you should be lenient.
