can't you just screw over a bunch of people (if the contest allowed hacks) by going on alt accounts, solving the first problem early, lock the problem, go hacking problems, and then start copy pasting and submitting other people's source code onto alts and act as if they plagiarised?

i hope it's not a thing (i've never hacked a solution real time before, but i mean u have to be viewing some source code while hacking right?)
