Now before you start flaming, I don’t feel they were perfect, as the mistake was to provide additional benefits to paying users, this doesn’t work as bots are obviously also paying users.
There’s at least one other mmorpg with a successful system with locked trade such as Black Desert Online. Frankly the issue is they’re giving trade options to token users at all when they should just remove them all together.
Silver should be untradable 1:1. I’d like to see 1:1 trading be reduced to pretty much valueless items like potions, antidotes, etc…
Capitchas should be put on the market. Frankly people whining because their friends can’t provide them handouts should go play the game, these people looking for an easy cop out seem to be your more likely crowd to fund RMT to begin with. Am not sure what determines min / max for these items on marketplace but obviously the amount of items atm without a cap is an issue. Need more space on marketplace also, 5 is waaay too low, 30 is a healthy amount and allow people with money held up on the marketplace to reinvest money into the market.
Add temporary 1:1 trade on fresh drops amongst party members of dropped loot for 1-2 hours so premades can distribute their loot.
Feel like the above would solve a lot of your bot problems because your previous solution wasn’t enough.
tl;dr
Remove all 1:1 trading except low cost consumables, capichas on market, temp trade option on loot dropped in parties (again, no trading silver so cant monetize this).
