I do understand that you are trying to help, but please do not accuse people.
I was told once in a PM that I was copying problems off a website, more known as AoPS.
(I was, in fact, trying some advanced problems one of my math tutors gave me. The problems I post here are the ones I have pondered over for a long time.)
(I also am posting work on my questions when possible.)
Needless to say, your contribution to this website is deeply appreciated, however, I would like to ask people to help people out, but encourage them to find their own solution by simply posting hints.
Please ask yourself in the future whether this person may be genuine.
