I think I remember that being what 60% to be considered good enough to be a member of staff.  I just think a lot of users will avoid reporting controversial content just because they are not 100% sure and could get a bad report. That's not the way they should be thinking if they want to be a moderator, rather they should focus on helping out the forum rather than focusing on accuracy and rather the reason given and how much detail and effort was put in.  

So don't panic if your accuracy isn't very high. To be honest you've only reported a very small amount so the accuracy will fluctuate very easily if a mistake was made etc. When you reach the 1000+ mark it seems like you've broken it because it won't move for months on end.


On topic: Seems like there isn't any limit and doesn't matter how many characters you put it won't become a problem visually for the moderators. So including my links to other sources should not be a problem from now on.
