If the forum still has patrollers then they can do this job.

Also posts that are off topic are meant to be reported by other members and can be dealt with by the moderators. If something is false and the mod doesn't know if it is false or not then it may be helpful to have someone who does but I don't know how this functions (it's likely if a member the mod knows for knowing stuff about a topic and being level headed reports it, that report will likely still get handled without the mod necessarily needing to understand it -especially if it's reported several times).
