How Do I Report Suspicious players on the MB?

So, I don't craft. But I make my gil playing the MB. I average 50k-100k on a slow weekday, 150-200k on a busy weekday. And I average 300-500k per slow weekend day, and 500k-5mil per busy weekend day. I've averaged this income for the last 4 months.

During large patches I average 2mil-4mil per day (Insanely busy days).

Now, A few of the items in my MB portfolio are Crystals. And I've been keeping track of retainers who consistently push there product in my products market- example Wind Shard.

Now, I've noticed an individual with near Identical retainer names for the past 4 months. And every 72 hours he acquires 50k of various shards,crystals,clusters. And floods the market.

I'm cool with that because I've made millions of gil off of this guy because he floods the market with no regard to what an actual person would ask. Example Water Cluster that's selling for 700g, he dumps 20k clusters of various sizes at 60gil each. (who does that?).

Anyway, he's been doing those type of shenanigans for 4 months now. So I'm noticing bot type behavior. How can I report a person for suspected botting when it's being highlighted as a major red flag on the MB?

Also, I'm pretty sure bots pool in there resources and send it in the mail to various other accounts that aren't actively interacting like the bots farming around FF14.

Such as, 12 bots are active in the world killing mobs/leveling up, or gathering materials. Then after 'x' time, they're scripted to port to a mailbox, and send there inventories to another bot who's just sitting at a mailbox and receives the product, and sells it on the MB (I would say they would have to have 1-3 bots that are dedicated to selling product).

That way, when the bots who are reported and eventually kicked (the ones actively gathering/killing monsters), they don't loose much because there product/gil is already dispersed to there Command and Control (C2) bots who aren't being reported.

Presumably the same way you report anything else. The problem with that is that the resources required for the investigation most likely exceed the allotted resources that could be spared for such an investigation.

He got his money, you got your money. Aside from running our of money to protect your market, whats the problem?

My opinion is, complicated.

I have no idea what the background these botters come from. (An individual living in the US/AUS/EU who is living in the basement of there parents house, or if they're from a nation that has weak currency, and $1usd=100$usd;equivalent in there country). Nor do I know what there actual sales figures look like irl. Such as, how much gil people buy per weekday/weekend/on holidays. So as an example this is what I was imagining in my head the other day:

1.) 1 mil gil = roughly $2.88 USD
2.) Selling 10 mil per day= 28.80USD
3.) Per month they would average $510 USD

As a closing comment, there's no real way to combat these individuals. They're offering a product that people are willing to trade irl currency for make believe currency. It's relatively simple to make a new account. So no matter how often you ban then, they can keep populating.

And as a business, I would bet 100$ they're smart enough to have a C2 element that stores there gil/sells the items. And those characters aren't getting banned because people don't report players who just sit at the MB/by the mailbox.

Like, you could ruin gil sellers businesses if you found out which accounts of there's held the gil (Follow the mailbox log between bots). Would take 1 day of checking backlogs (vial mailbox transactions) to figure out a network of botters. And to also figure out which accounts were buying the gil (consumer).
