This is exactly what I mean, thank you adding another perspective.
Basically, I think it's SE's responsibility to prove the person is guilty, not the player's responsibility to prove their innocence.
Just playing devil's advocate, but I know I've mistakenly been in battle and clicked "accept" on those annoying weird name friend requests without paying attention // didn't notice till I checked my list later to see if a friend not in my FC was online... I truly wish they could have a 'decline all friend requests' option somewhere... like turning off PvP in some games.
even if you accepted it, it would then require you to accept the gils from the mail, you could delete it and tell a GM what happened to be sure, reducing even more the chances of being framed, that would only work on really noob players that wouldn't even know what a gil seller is.
Hate to say it, but one of the better ways of getting rid of RMT is SE selling their own gil... that way there's no point for RMT to exist here. Though that said, I don't think the RMT is that bad, yet, course its hard for bots to make new chars on my server so its not as big a deal here :o
So would you rather be spam'd by bots to buy illegal gil, or have buying gil a legit option offered by SE and deal with the pay-to-win people (though really in a PvE game who the hell cares?)
While I would actually do exactly that (send GM mail and not even touch the mail), there are probably some people who would just accept it because, well, easy gil and not enough intelligence. It is those people I was referring to who could lie and say they didn't buy it, even if they did. Sure, they'd get it taken away, but they couldn't really be punished. There's just so many ways to plead your innocence since SE cannot prove anything at all -- all they can do is take away suspicious gil // and all of the time and expenditure to police this kind of thing is something I don't think SE wants to invest in - or they would have already. All of these GM interactions cost money, after all.
As others are pointing out, you can't prove somebody bought gil unless they outright admit it. All the person has to do is say "I didn't buy it. A random stranger just gave me this I don't know why." etc and SE cannot prove they are lying. It would be a very bad business practice for SE to just start banning paying customers left and right based on circumstantial evidence and gut feelings.
When a player receives a large amount of gil from a known gilseller (who collects gil from multiple bots), he will be given a warning not to do so again. If he yet again receives a large amount of gil from a known gilseller and not report it, then he will have a hard time convincing a judge or jury that he is innocent. Despite popular belief, a judge or the jury do have some level of common sense!
