This may be a daft idea, but I'm going to put it out there anyway.
To help combat bots on the front end, why not have player GMs who have the ability to ban the accounts of any gold spammers or bots they encounter in the game. That would be the only GM power these volunteer players would have, and they would only be able to ban spammers/bots. Any Player GM caught banning an actual player would have their GM privileges stripped, and their account banned.
Further to this, you can have player forum mods who can respond to the plethora of threads demanding CSR attention, but let's face it, CSRs just can't handle the sheer volume of threads, and not every thread needs a response from a paid employee.
In-game GMs would hopefully cut back on the amount of bots players encounter, and free up ZoS employees to find more permanent measures to end the bot nuisance.
Forum mods would allow players to get responses to issues that may have already been addressed by ZoS in another ticket, and allow the CSRs to focus on more important issues.
Thoughts? There may be issues with my idea, feel free to suggest changes to the plan.
