Accidents are EXTREMELY, rare in terms of flagging. almost everytime its deliberate.
The punishment should be severe, ur wasting the other persons time for no good reason, often in positions that are completely lost for the flagger.
Why would wasting someones time for so long and delaying as well as doing that in a lost position only warrant a small punishment? It's unacceptable.
The mods are exaggerating it. Sure, if you're stalling, maybe, but lets say you go on vacation and you just flag as an accident. A straight up ban doesn't make sense. Maybe a warning, but not a ban!
