You can't just pick an account and be able to hack into it. When people claim they were "Hacked", they mean they did something stupid and gave account information away, i.e; the email they used to identify (+ password, in some instances) or their GraalID.

Also, if you really want to take precautions, don't ask other people to upload for you. It's simple to do even if you only have 5 minutes. And just plain don't give out account/personal info.
