this happened more than year and half ago..
a guy had a crush on girl. the girl came to know abt it through rumors and didnt like him, told him to f**k off and convicted him of harasssing her
later in the lab the same guy was playing with windows remote desktop when he accidently connected to the PC being used by that same girl working hard on her assestment, when she unexpectedly got knocked out due to remote desktop losing all her work....u can imagine her reaction
since she thought he did it on purpose our IT teacher banned the entry of that guy into computer lab execpt ONLY for his lesson.. he is not to come into lab during free time for what ever reason.. hehe
ohh and this guy was a dumbass hacker-wanna-be and always messed the lab computers so i even put logon hours restriction on his user account.. he could only login during his lesson timings and kicked out when logon hour expires
