Re: No other options but to press "OK"
One possibility is that the intention of the bad spelling and syntax is to filter out targets with even a little skepticism.
It sounds logical. But writing malware, to me, would be a lot of stress. What if you get caught? What if you extort money from someone who can't really afford it, like someone's grandmother or something?
No. You write malware because you don't have the option of making a decent living doing normal programming, and then going home, and sleeping peacefully through the night.
The best reason I can think of for the lack of options, is that your salable skills are iffy.
