It's not a bug. There are limitations for every action (posting/reporting etc.). When you have enough activity you won't see these limitations.
As a newbie you can report posts as long as you wait for 10 minutes between each action.
What are the time limits on posting and the levels??
I know 360 seconds are for new people like me, but was wondering if there was break down somewhere on this.
waittime = 360;
if(activity >= 15)
waittime = (int)(90 - activity);
if(activity >= 60)
waittime=(int)(34.7586 - (0.0793103 * activity));
if(activity >= 100)
waittime = max((int)(14-(activity/50)), 4);
