Although it can or can be directed as a threat, YOSHIE seems to be very rude and aggresive on Royse777 on this matter which should not be.
If it was not a threat, why YOSHIE would bother editing his reply now?
There is some sort of conflict between them, which I can't be bothered to look into, and both are acting... not in the most mature way. But YOSHIE is hard to understand on a good day so it's really a huge stretch to interpret a vague statement like that as an intentional threat.
