Summoning Chaotic Entities in Towns
 

Is it okay by shard legislation for players to summon entities like energy vortexes, blade spirits inside guarded towns and mass-murder the newbies which train using macro, most of the time being away from the keyboard ?
I know it can be prevented by adding a simple message line (guards), but this kind of contradicts the message flooding legislation. Imagine 20 newbies, all flooding the town with "Guards" messages. That is quite disturbing.
Thank you for your time.
