I believe that RMT-bots plaguing FFXIV players by spamming /Tell messages is a very annoying occurrence during gameplay.

To help counteract this, SE could change it so /Tell is restricted until a player reaches Level 5 in any class. This would not be a very big problem at all to new players who can still use /say, /shout, ect; but this Will be a hindrance to Bots, as it will require human input to level a character to 5, rather that it being entirely automated on the RMT-Seller's end. Bots could still use /say and /shout to advertise, but they would be reported far faster and by more people than with direct access to /tell.
This would also help relieve the annoyance of bots sending a Friend Invite to hinder players from using the Blacklist feature.

I know that this is not a permanent fix, but I believe it would help slow down the creation of bots, and other accounts created solely to partake in illicit activities.
