Ohai, you must be new here. First of all you can circumvent to 1000 char limit by using the "Edit post" ability.

You are not the first person to complain about this. I don't know what is going on about the RMT problem, but there are a few things you can do. 1) Don't buy gil. 2) If you don't anticipate getting a /tell from outside your FC and linkshell channels you can use /busy to block all tells, 3) If you see someone doing obvious botting (like say 4 people in the same outfits auto-killing the same mobs), initiating a trade with them will get the botting hack to stop; bonus if bot in mid fight, which will cause mob to kill bot. 4) Report suspicious activity using the Support Desk, and point out said suspicious activity to other players and encourage them to do the same.

Oh yeah, and don't buy gil.
