Some people on this sub-reddit just don't know how flairs work
I don't mean this to insult anyone. If you still find it that way, then I'm sorry.
It's just that, when you're looking at some of the posts here, it can be a little confusing of what exactly the OP actually wanted. The most common thing is mixing up flairs. You see someone asking for fanfiction recommendations, and if it's something that you have read before, you would just recommend it to the OP. There doesn't seem to be a problem. It only might becomes confusing when you click on the post, and see the flair. On this sub-reddit, when you are asking for recommendations, you would use the "Request" flair. Seems easy enough. But from what I see, some people mixing this up with the "Recommendation" and "Find That Fic" flairs. "Recommendation" is an understandable mistake to make, since you are asking for recommendations. It's just that this flair isn't meant for that. "Recommendation" is used when you, the OP is recommending fanfictions to others to read. While "Find That Fic" is used you are asking for a specific fanfiction that you (might) have read before, but you don't recall the title (and/or the author). So this one makes a little less sense of why would they use it when they are requesting for possibly multiple fics.
I could imagine that those who have made these mistakes are still new to this sub-reddit. I mean, I have first found this sub-reddit back in the late 2010s, and even I made similar mistakes back then, because I didn't know what each flairs were meant to be used for. As hilarious as it sounds, I only noticed that is a Flair Descriptions page a few months ago. Though to be fair, I don't think that many people actually notice it at first.
