I finally did it... disabled tells with busy status. RMT unbearably bad.

I played EVE online for a few years. One of the best features for dealing with RMT:

Right click, report RMT. Removes all messages of that player from your chat log and you don't see any more messages from them, but the block is separate from the blacklist so it doesn't fill that up either.

Can we get something like this in XIV?

this, so much this
