We anticipate that even with this update, third parties will continue

This might sound nutty but have a in game system for RTM so puts RTM out profit in some way.

Bring the Cash shop in game not an external website.
Give all players a #account name outside character names.
Let players send gifts to players in game to the #account name and not a code.

(Radical change biased on GW2 system)
Next is then make a Crysta the default cash shop currency that all players need buy with real money.
Set up a Trading Exchange that lets players Exchange Crysta for gill and Gill for Crysta. The value on conversion should always change biased on supply and demand of Crysta to gill.
Crysta to Gill should always be Pricier than Gill to Crysta.
You also block all cash shop and Exchanges on Free accounts and make so new accounts need a 7-day validation period before they can buy off cash shop with a new account that's not free account.

Also set a weekly / daily limit on the amount gill a player can trade to another player.
Add more free account restrictions to chat

Making everything internal will block External.

Just keep sub to real currency and can't be brought with in game Crysta that or make new currency type.

It might not work in FF14 but the place seen it implemented it works pretty well in as hard to make profit off as everything internal can only really then sell accounts.

You've essentially replaced "WoW Tokens" with "Crysta", for those more familiar with World of Warcraft than Guild Wars 2.

GW2's in-game cash shop doesn't prevent me from logging into your account. It also has the disadvantage of using a saved credit card if one exists for your account (paypal is pretty much the same) to purchase Crystals. (The 'preview' button appears to have issues online at this moment).

TBH nothing's going stops that people logging into your account if you let them so can't do much about that RTM.
only thing you can do is put in regen login locks but that's very extreme by monitoring suspicious activity.

also, they don't need to save that info really down to game devs if they want to or not but permit that option just cues ease of use

but the approach overall is a layered system, changing one thing won't help.

I suspect that is why the Mog store always asks me for credit card information. The devs for the store (who are not the devs for the game) do not allow it.

Pretty much SE always been hard RTM but at the same time not they just always handle it poorly. but definitely been good about account security but even that fails.
Probs why need to get bit more extreme but not so extreme they limit the player base.
