It's been proven that bulanula was overpaid, so he's ethically obligated to return the extra BTC (minus a few percent for the inconvenience, perhaps).
I admit that "scammer" might not be the most accurate term, but creating a new tag would be inconvenient and "scammer" is close enough.
So is getting new forum software, I see !
Why not give me this caution tag here :

This was in no way a scam.
Guy overpaid, I refuse to give refund to assholes that attack me publicly and can't read numbers properly, I give him service instead of money back.
There still is no scam. Maybe the 25 BTC was a donation for all I care. I did not force him to send me anything. I may be an asshole but he started it.
I am not a scammer and the scammer tag is bull. I am not even trying to sell anything anyway. I am sure that if I do then people will point others to this thread.
Just give me that caution tag already, please !
