You have to find out why the computer center is mistaking OpenGoo with Project Pier (how does it perform the detection). Then we can tell you what to change to avoid it.
Cheers.
Because I am not the person who directly have a connection with the people in the computer center, it always takes some time to get the information.

Besides, it seems that the person who sent the warning to us is not a technician but a normal staff getting the results from the computer and sending errors/warnings to the corresponding person.
According to the news I got, it seems that the computer center has a cooperation with a company which analysis the open services inside the university domain and compare the pages, e.g. index.php, with its inner database to see if there is any suspicious patterns. And, this is the reason why the computer center mistook OpenGoo with Project Pier.
I know it's not a such precise answer but this is the only one in my hand.
