Forget sentence analysis or group fee, only way to kill the spam is to kill the moron-power that funds it. How? That will take 3 steps, and might seem like a "too big a system change to be feasible" but shouldn't be, RLV (somewhat) already does the hard part client side. 1) From now on, accounts without payment info on file don't have a wallet, they have an escrow. They could still ask for the money, but they can't transfer it, nor withdraw it. There is no financial gain anymore. Only thing they can do is spend it on predetermined sellers, which are those either already moving a lot of money (you can define which and update the list with one db query a day), have a long standing MP or casper or allomancy or whatever with KYC themselves on the destination point, are known brands or registered with LL on some form. The idea is to only allow spam money to be funneled into known and approved user uuids. This part is a control over the payment system, takes (origin,destination) and resolves to a boolean. "But how about all those newcomers that have friends in the game" you ask? If the vendor isn't in the approved list, at least every vendor has a 'gift' option. Wanna pull more resources? Send it to that old friend and he gifts it to the new account. Is it an Alt? Same idea. 2) Track the wallet value once payment info is added. Sure, once spammers have enough, they could add a CC on file and ... nope. The amount they had when escrow ended still will be treated as escrow money even after payment info is there. Only way to "reset" it is to spend on approved vendors until 0L, and from then on is all wallet money. (this part can be added on top of existing systems) 3) Call the Legal team. This is the fun part. Add something like this to ToS. "Users are strictly prohibited from using the platform, including any messaging, communication, or content distribution features, to engage in the solicitation of money, donations, or other forms of compensation in a misleading, deceptive, fraudulent, or spam-like manner. This includes, but is not limited to, impersonation, false representation of need, or the use of mass unsolicited outreach for the purpose of monetary gain. Each instance of such prohibited activity, as reasonably determined by the Company in its sole and absolute discretion, shall constitute a material breach of these Terms of Use and shall subject the offending User to a liquidated damages fee of fifty U.S. dollars (USD $50.00) per violation. By using the platform, the User acknowledges and agrees that this fee represents a reasonable estimate of the damages suffered by the Company due to such misuse, which would otherwise be difficult to quantify. The Company reserves the right to enforce this provision through any means it deems appropriate, including the assessment and collection of said fee, suspension or termination of access, and referral to law enforcement where applicable." In short, if they add a payment info later on to try and liquidate the spam-earned assets, YOU charge THEM instead. Is this a stupid idea? Probably. But it's an idea. /me grabs popcorn
