The RMTs are everywhere. :/ Blacklist them and move on.
As Adrian noted, at least *now* they are only on the tells. They used to spam shouts until SE put in protections against that. I don't recommend blocking /tells altogether though. Occasionally someone wants to message you for a valid reason .. like asking questions
They seem to go in waves and I suspect rotate between servers. We (on Malboro) seems to be having another wave right now.

In other news..
Welcome to Eorzea and Malboro!
Look me up online if you have any questions. I'm in Gridania a lot of the time so we may have run past each other.
One of my FC mates posted this thread a couple weeks ago for anyone new to Malboro and there are some other people who have offered to help out new players listed on there - http://forum.square-enix.com/ffxiv/t...s-on-Malboro-D
