The worst is when someone of long-standing good repute just disappears. I can’t recall who but I remember a few years ago a guy whom owed thousands in currency and product disappeared for months and months.
Thankfully (yet sadly) it was found that he had a major health issue and then everyone felt like shit for black balling him.
The funniest are when some guy makes his 11th post selling a “super franken” or at least trying to. Live the classic “friend, you can trust me friend.!”
