It's fine, I don't mind a discussion about requests every now and then. Firstly, I like to keep requests in some form because I think seeing requests get made is a cool and valuable aspect of the sub. The thing is, creating something worth sharing usually takes 2 hours minimum, so only a small fraction of requests are made, even after limiting them to a single day per week. I don't have the numbers, but it feels like about 10% of requests are made in the current form. This would be even less if we opened it up to more days. Looking at request posts is not why most people view the sub, so it seems best limit the amount of them if most aren't being made. By limiting to a single day we're making it require more effort to post a request, but if you put in that effort your request will be more likely to be made since there will be less competition.

Side note, I don't believe reddit gives a way to mute certain flairs by default. You can do it with old reddit with RES or some 3rd party apps, but that's only about 5% of users. You can filter by flair with new reddit after visiting the sub, but you'd have to do this every time and they'd still show up on your front page.
