More and more people are just removing /shout from their tabs, the gil sellers are really starting to get out of hand, they're multiplying very quickly and something really needs to be done about it asap or it's going to become the worst thing about this game.
Some solutions are:
1. Add crysta as an in game item you can sell on the market.
2. Restrict /shout and /tell to level 15+ only.
3. Add a flag so when a character is put on the blacklist of a set amount of people (let's say 100 people), they automatically lose /shout and /yell until they contact support to clear it up.
I know none of these are ideal solutions, but the gil spammers are getting progressively worse and something needs to be done about it very soon.
