Sorry, but this isn't a good idea. Hitting 300 good reports isn't that hard.
Yes, of course! It is possible to send
300 reports in
1 day!
Then we need to increase the number to get the badge. How about 30k report as the first milestone for the badge?
I think 300 is enough, it's possible for those people who has the knowledge on what posts to report. But if you're not quite good on reporting some shitposts then maybe it'll give you many bad reports.
It's just an additional badge or maybe an additional challenge for us to diminish all the shitposters in the forum. For me, the green trust is the greatest reward to achieve by each of us.
