And still every night, I have RMT tells spamming me before the game even finishes loading...and then at least one tell per 2-3 minutes unless I'm busy or in an instance.

No one is disputing that they are doing something. The problem is that what they're doing is not effective.
Many people have suggested solutions that have worked in other games but they continue with the same ineffective ban waves.
I've played many MMOs...WoW, Everquest 2, RIFT, LOTRO, Guild Wars 2, for example...and the RMT spam on FFXIV is the worst that I've seen on any of them.
