It's expected for now. RMT have been increasing their advertising lately, so it'll eventually blow up in SEs face whether they want to ignore it or not. Once RMT have too much supply of gil, they'll do a sale that's just unbelievable and almost stupid of the player base NOT to take part in it... assuming of course there's no fear of keylogging and the like from their sites. That's exactly what happened with FFXI at one point in time. Until that time comes however, yes, it's normal in Asian MMOs. SE's outlook on communication in general is odd, to say the least.
