Interpret it this way please: Thank you for your offer, I'm not interested.
Do you even even know what the word "scam" means? Making wild accusations without prove is
just BS
Yes, I have some clue, I was scammed here multiple times, that's why I am rater risk averse.
What is your first thought when someone sends a pm to you, stating that he won't send first, and a quick search for his username results in scam related topics?
You can call me overcautious - but these were red lights for me. Him calling me a scammer makes it even worse (try to find ANY proof of that)
