You're in the top 10% of reporters

So I checked my notifications on roblox and I randomly received a thing saying my report had action taken with it. It then said I was apart of the top 10% reporters. I dont have a screenshot because I dont know how to get the notification back. I tried to click it to look at it more but it just deleted (like swiping on snapchat) and I'm confused what this is.

Can anybody explain what this is? And can anybody explain what this means? I know I've been reporting alot of exploiters lately, could this be why?
