In my life I have always had to listen to lies that get out of hand and bits of exagerration which means over the years I have become a world renowned authority on bovine scatology.
You own the trademark PAYP yet you got an offer of $1400 for it and you think that is interesting?
You are so full of bovine scat I am actually starting to like you, claiming to have a trademark is one thing, thinking you can defend a bullshit mark so you can keep a domain hack which is only a thinly veiled attempt effort to squat on one of the seminal leviathan companies of the internet (Which is owned by THE original company which is extremely aggressive in chasing its marks) is either insanity or stupidity; I just have not figured out which yet.
Delete it and do not take any money for the domain.
