I agree with this. I actually made quite a heartfelt post regarding the recent events that made some pretty notable people leave. It was actually already done several times by other members by that point, so really it was a shared sentiment by me. It lasted on the front page where it could be easily viewed for about 4 minutes before a cacophony of birthday post to people that never even have posted in the first place cluttered it up, and sent what I shared to the main profile post page aka shadow realm.
I think a good solution would be that after you provide your birthday its not publicly displayed at the bottom until you make at least 25 post/reach level 1. Birthday post, especially in the abundance it proves to be, should be more of a community based thing, not also for people that solely show up to grab a couple of roms from the repo.
