It was a tough decision, but I've come to the conclusion that I'll leave negative feedback for you. For the moment.
I promise to delete it once I'm somehow convinced otherwise (maybe your proposed transfer of a minor amount of BTC will do the trick, but we'll see how much it turns out to be).
Please try not to take it personally.
This could be pointed as an trust abuse, you could make the tag neutral, until it is proved. Yes, negative trust would not effect me, but you know it shows bad repo of a person and I cannot bare it as I have not done anything scammy here.
