BEST PLAYER Event Round 13

Regarding the 13th Best Player event, the previous event gave 2,000 Cash for 1 post and 3 comments, but this 13th round says 2,000 Cash for 3 posts and 50 comments. Do I need to write 50 comments? However, before clicking on the ongoing event, it says 3 comments. Which one is correct? I don't know how to write 50 comments, and there is no customer service email or anything like that, so I can't ask.
