I'm glad that you and him have actually spoken and that you were both able to get your points across and learn some things you weren't aware of. This seems better than ranting in angry posts (although we'll see what the future holds there. More so for him than you). 

There is clearly a demand for minnowbooster (and randowhale before he went into permanent sleep) and of course, people are going to look for loopholes to exploit them because there's a financial incentive to do so. I'm glad that you are keeping track of that and fixing the issues as they come up. Let's face it, there's not a lot more you can do since you can't anticipate every single issue. 

I would also question those who think it's unfair you get paid for your services. How does giving all your time and skills generate new and better products/services? Financial incentives breed innovation and competition. That's just the way it is. I'm also guessing none of these people would do the amount of work you do on steemit for free.

So thank you. Keep up the good work.
