Yes, everyone sees it. I'm pretty sure it's because instead of everyone coming up with their own flavors, it's a lot of people asking for clone recipes.
I made a thread on it a few months back, to make a separate subreddit, mega-thread, or outright ban clone requests, but nothing came of it.
I don't mind it. I've requested a clone before. But a seperate sub would be overkill I think. It's still technically all DIY. Maybe if more people used the clone threads?
I know a separate sub would be overkill. My personal problem is with random people looking for a very specific recipe, that aren't into DIY at all, coming in here just looking for a recipe for one juice. I don't mind the people who are actively working on a recipe and looking for input or ideas.
I do realize this would be impossible to police. Another problem is the fact that reddit archives threads after 6 months if I remember correctly. Because of this, users can not vote or comment on these older threads.
