+Both in-character (IC) and out-of-characters (OOC) threads have been included, but in most cases there is no direct way to recognize them except by thread title. I strongly advise to filter OOC threads out, as they can cause coherency issues when directly finetuning models on them. For example, oftentimes users can randomly refer without context (other than posting date) to ongoing events in the corresponding IC threads, and while they might know exactly what they're referring about, the LLM would have no clue.
