I have a feeling what we're going to see as the first change to this is a reduction in the amount of damage that needs to be done (which will be either 3.15 or 3.2, no sooner). Nothing to do with kicking people and all that. So basically, leechers can continue leeching. It always takes at least a few tries for the devs/Yoshi-P to get things to be at an acceptable level. They're so pathetic in that area of being naive, when it comes to trusting players, that it's very laughable. They never learn... ever. Then again, they likely don't care to on that regard. Probably won't see any concrete changes until 3.3.
RMT: Getting bombarded by /shout and /tell spam = Weak chat filters put in place and players are told to report in a poorly made report system.
Wolves Den: win-trading = "Please stop win-trading"
RMT: Getting /tells and Friend Request spam = Report using poorly made system and "Look!! We ban accounts!!"
RMT: Still getting /tells and FR spam = "I said LOOK! We ban accounts! We're obviously doing something to combat the infinite wave of RMT inconveniencing you by banning accounts that won't stop appearing again! You don't need chat filters, you just need us to tell you we're banning accounts!"
Triple Triad: People are win-trading = "Please stop win-trading"
Bots: Blatantly obvious, abundant, and occasionally found using hacks = "What bots? You know it's impossible for us to track them, therefore, they don't exist. We're going to ignore this report you spent the time making"
RMT: Friend Requests no longer as much of a problem = "See? It tooks us around a year, but we finally found out that a big part of it was our Free Trial accounts being able to do that. Who knew!?"
<prediction of initial response> Diadem: People are leeching because we can't kick them and reporting is useless = "Please stop leeching"
<prediction of initial response> LoV: People seem to be win trading and being good works against you = "Please stop win-trading and please find ways to have the system work in your favor"
