Adam made no such decision.
Ah, shit, wait. I thought you knew. I did make the decision to shut down zomg. About a month or so later, the host removed it as well (for "adult content" lol). I don't know if that was as a direct consequence of your report, but I doubt it. Either way it would have made no difference as I wouldn't have brought the site back afterwards. I might have considered it at the time, but with hindsight I can say I wouldn't have done
I dunno if you were around when Flake was attacking the site, but iirc he tried to report the place shitloads of times too, and nothing happened from it. I reckon unless someone reports cp, then they don't take it too seriously .
Regardless, whether you'd sent the report or not, I still would have shut down the site when I did. I'm genuinely sorry for the person who really did get a lot out of the place at the time, but it needed to end. It ran its course and went to shit long before I shut it down. I could name a few people who possibly contributed to that, including myself (for neglecting it towards the end), but I wouldn't include you in that list.
I don't think you are in any way responsible for the end of zomg, and I should know.
