the issue is the only server i have a character on that isn't spammed is Balmung, but the downside is none can make a character, as long as the RMT gets suckers or response, then they see a profit, if they weren't making profit they would stop :c and all they need to be considered a profit is someone buying gil from a 3rd party, or gaining something from the 3rd party, WoW was badly affected by this were people could buy 100gold by paying £40 (it was even on the news back in 2008 in the uk)

the best thing you can do is go on /busy or ignore them as best as you can, the thing SE can do is have an option that says "only allow tells from friends" "white list tells with the following words" "only allow tells from anyone when recruiting for PF" those 3 options would allow a lot of the RMT spam to be deleted, it wasn't as bad as 2.0 where they spammed Say Yell and Shout D: i am glad those days are gone.
