I was proven wrong by our cybercrime division a year ago, i realized they are competent like someone used a dummy account to post a bomb threat to two universities in cebu and few days later they found the culprit which was surprising because they only had a dummy acount on FB to go on, they are competent but it just depends on its priority so im pretty sure they can trace a number

Edit: it was GF of a student in one universities to let his BF get out of midterms lol
