They won't decrease your accuracy unless they are marked as bad. The reports are neutral until they've been handled in one way or another.
So there isn't neutral reports? If a person reports a post for moving a thread to Project Development but the staff moved it to Digital Goods. So is that post good or bad?
No. The only way it would be 'neutral' is if every mod 'ignored' it but that is unlikely to happen as someone will likey handle it or mark it as a bad report at some point. And whether a mod marks a report that is moved to a different section than reported as bad or not is up to them but I think reports are sometimes automatically 'handled' ie marked as good when they're moved to a different sub.
