Well, as far as a mate begging or just begging in general going to far like that, it is relatively common in any gaming platform. Sadly, this is even more common with role-playing games. Some individuals who play these types of games that it too seriously especially in a RP session. I see this many times:
Friend: -does rp post-
Their mate: Wana be real mates, like ooc?
Friend: ??
OR
Me: -does rp post-
Partner: -makes a face-
Me: [Are you alright?]
Partner: [Do you really love me like that?]
Me: -starts to get nervous OOC-
Partner: [Tell me! Or I'll stab myself]
Unfortunately, their threat to themselves really happened and they were sent to the hospital afterwards. -was stalked for the next few weeks-
Things like this is just the inability to separate real-life and a simple game. Although, I will also see for some people who believe that the cyber-world is the exact same thing in the real-world, nothing different at all. And with this in mind, it confuses others as well as disturb the person who are playing as their partner.
