It's an option, do you think that it'll get a lot of views? I've always dreamt of being cremated in a gold plated casket.
How much debt do you want to put your family in?
To make an example of my point:
your 1st prank:
High chance someone just closes the browser or changes the webpage. Or, better yet -- simply doesn't care.
2nd prank:
This is funny how?? You're annoying customers. That's not funny, it's blatantly annoying and a possible disruption of services.
You'd probably just be told 1 sample only in most cases anyways.
3rd prank:
...What?
That's not even funny. Most kids and people on the internet will not give a stuff about that.
You may as well lock this and admit you aren't doing this because you'd never get popular from any of this.
