If the referee speaking to the media has taken action at the time and reported everything to county then he has my full and absolute support. If he hasn't then you have to question what is going to stop the offender from doing it again, and again, and again?
As I said before, I do speak from experience here, as I have lost count how many times I got emails from referees complaining about the conducts of teams, managers, supporters, etc, only to then find out that they haven't reported a single card or misconduct after the game. What do they expect me to do, I wasn't there so can't do anything.
When I was an inexperienced referee I used to struggle badly with dissent, and that is because I either ignored it or cautioned for it, there was no middle ground. These days I get few problems with dissent, that isn't because I get every decision correct, but rather I cut it out at source and make it clear it isn't happening in this game. That doesn't mean using cards necessarily, less than 10% of my cautions last season were for dissent, but I don't ignore it which was always my problem before. You have to be preventative and cut it out at source, not reactive and throw cards around.
