Failure to maintain in-character behaviour during a roleplay interaction. The broad bucket for actions that break immersion: ignoring obvious threats, doing impossible feats, or breaking character for out-of-character reasons.
Fail-RP is the largest category of light moderation actions on a roleplay server. It is also the most subjective: where the line falls is community-specific. Most servers issue warnings for first-time fail-RP and escalate to bans for repeated cases
Because fail-RP is judgment-heavy, case files for it tend to be note-heavy: a timeline of staff observations rather than one attached clip. The case timeline format suits this well.
