Are we only allowed to report twice per thread?

I was trying to report stuff in a thread that started discussing "mature content" and breaking the forum rules. Only the first 2 posts I reported changed from "report" to "reported."

So I logged onto my smurf, and sure enough, only the first 2 things I reported worked again.

So I logged onto smurf 2 and reported 2 more for a total of 4 reported posts (since the first smurf ended up reporting the same 2 posts for testing purposes to see if it was really broken), but I think there's still more...

EDIT: seems like it's a time limit. Waiting a minute let me report more. I think I got them all now...
