The way I see it, this case is the wrong choice. The firmer hand the better option, if they run this with as many Kuroko circles in, the psycho will have no choice but to show up at the venue with his whatevers, this will prompt a look out for the police, with that many eyes, he may lack space to maneuver and if he has ever been to one of these events he should know, it is literally chaos outside and inside the halls. At best with whatever methods, security can be tightened 3-fold and patrols on every corner. This way, it shouldn't be hard to spot something amiss especially if they print out what he has posted so far, his descript should provide ample guide as to how he looks like, unless he is a cosplayer... or typically any smart fool who intends to do this will dress up in typical Otaku dregs, then it might be less obvious.
However, once you cave in, the second and third will come. I am hoping based on the dovishness of the typical Japanese grudge-keeper they wouldn't do this like this guy.

Da way I peep it, dis case is tha wrong chizzle. Da firma hand tha mo' betta option, if they run dis wit as nuff Kuroko circlez in, tha psycho will have no chizzle but ta sheezy up all up in tha venue wit his whatevers, dis will prompt a look up fo' tha five-o, wit dat nuff eyes, he may lack space ta maneuver n' if he has eva been ta one of these eventz he should know, it aint nuthin but literally chaos outside n' inside tha halls fo' realz. At dopest wit whatever methods, securitizzle can be tightened 3-fold n' patrols on every last muthafuckin corner. This way, it shouldn't be hard ta spot somethang amiss especially if they print up what tha fuck he has posted so far, his fuckin lil' descript should provide ample guide as ta how tha fuck he looks like, unless he be a cold-ass lil cosplaya... and typically any smart-ass fool whoz ass intendz ta do dis will dress up up in typical Otaku dregs, then it might be less obvious.
But fuck dat shizzle yo, tha word on tha street is dat once you cave in, tha second n' third will come. I be hopin based on tha dovishnizz of tha typical Japanese grudge-keeper they wouldn't do dis like dis guy.
