You shouldn't be accessing your acp in a "shared environment". Not just that but someone will not just be able to obtain your session id it would take a fair amount of incompetence on the admin's end for that to happen.
I'm sure you would also not appreciate people spreading misinformation.
I could have handled it nicer however he/she could have written their post more accurately like saying "I haven't noticed any bugs. I think my board is perfect." instead of trying to state things as fact like he/she did "Well, i dont have any bugs on my board".
Clearly, there are bugs just take a look at the bug tracker...
