Guidelines for DD posts

Is linking to an external DD post allowed or is the DD forum more for independent DD? I’ve found a play that looks interesting but the DD is already done from a different Reddit user, could I link to that in the thread?

DD’s are never already done, you could always add your personal thought as to why that DD is even worth posting and any info you can find that is not on the DD. I’m not against it as @Conqueror posted one from reddit today here [Reddit DD] TDOC potential new customers DD

Just be honest about where it came from and copy the body into the forum so people don’t have to go elsewhere to read it. Nothing wrong with it.
