Can I ask where do you live?
I live in USA.
Yes, right now, jurisdictions matter.
But if a movement gets strong enough, they could petition the United Nations to create and enforce a ban on sites like this. A nation, who is a member would be persuaded by the UN to enforce the law.
Of course, there are ways around that, as well, but it is still another hassle.
Best to stay out of the news if at all possible.
this laptop was a gift from my mom
All the more reason to make sure she does not find out you were on this site before you ctb.
She will blame herself as causing what happened.
I am sure she was not your reason to ctb, nor do you want to guilt trip her.
Destroy the computer, and set it out for trash collection.
Chances are, if she gave you the computer, she will not re-sell it anyway.
Better to miss a laptop, than get a lifetime guilt trip.
