You really can't use the exact name of the people you are cloning. Even something like "stackrobot" would risky. Safest thing is to not use any words from the original product.

IANAL
Source: Ages ago I had a personal domain based on a longstanding nick that happened to partially coincide with the name of a major motion picture studio. That it was a paralegal who called me said they weren't anxious to take it seriously, and all they were really after was just getting me to say it was nothing to do with them so they had me on record in case I later did make it something to do with them. No big deal, but it wasn't like if I had a treatment burning a hole in my pocket I could've parlayed the conversation into a chance to submit it. And even at that, I doubt this will be anything like so simple and nonadversarial.
Of course. Here's the plausible chain of events:
1. Someone at the co. reads about this on HN 2. They tell their boss who might tell their boss, etc. 3. It finally gets to someone who is responsible for telling the lawyers. But they also say "hey this is kind of cool. We'll send a C&D, but maybe reach out to see if there's anything interesting there."
(Not least because escalating something to counsel, and then having side conversations about it with whoever you just brought to counsel's attention, is a bad idea!)
And that's if they see something here they might want to investigate further, which given SO's stance on ML-generated answers up to this point, I tend somewhat to doubt.
I have, in fact, seen this exact scenario!
I don't think it's likely, but losing a domain is a small price to pay if that were potentially a goal.
Deliberately infringing someone's trademark with a domain name seems to me like a dicey way to look for attention, though. But hey, "it's a bold strategy, Cotton, let's see if it pays off for 'em."
But you could start a company called Stack Overflow that sells cookies in Austria. They may still try to sue you but then it comes down to an actual argued case and debates and such. This is just complete copy.
