Come on! This is homework!
Let's see how I can make a response to this unreasonable, unprovable assertion without being unreasonable or irrated.
approach one: the personality appeal
Well, it is not homework. If you knew who I were
you would know that I am not in school.
approach two: the common sense approach
To me, the question asked just seems like a question asked. Is there something about this that sounds like homework? How do you distinguish a homework problem from a non-homework problem? You certainly were pretty confident of your assertion.
I'm really rather disappointed in you. You have made some great posts in the time I have seen you here, and now you want to say something that (a) you cannot prove (b) is false.
approach three: the prior evidence approach
If you look at my home node
you would see that I have a long long history of posting, and most of these posts show evidence of professional work... which does not preclude returning to school.
the next approach: pure logic
You cannot prove that this is homework. To do so would require evidence that you cannot find. I also cannot prove that this is not homework. To do so would require evidence that I cannot produce.
the final approach: ignore him.
He is making unfounded accusations. Of course, this hurts you in a few ways: (1) it led to a huge number of downvotes (2) it makes you look crooked (3) he might treat you like a person trolling for homework help in the future.
All in all though, what can you do? It's a shame when someone tells a mistruth and has no evidence for it and then insults you in the process. But why stoop to his level? In terms of etiquette, he is acting poorly... he said "no bone for you" --- he's calling you a dog indirectly. He is out to humiliate you. His Perl skills are fantastic as he has shown in his posts. But that does not excuse his illegitimate and hateful attack on you.
Seek a better company than he provides and hope that he will join you there someday.
