The platinum sponsorship was a quid pro quo for the speaking slot last year. That's how it works. Every placement they've ever had they had to pay for, including the 2018 interim data report in the Journal of Transcendentalist Superstitional Fantasy.
This whole thing is a frigging scam, and the company is now in hiding. Anyone should be able to see they made all of those promises last year and then they got a whiff of the data. Oof. Time to go underground. You'd think for once they would do the right thing by posting the failed TLD, but no. They just can't bring themselves to put an end to it all. The people running this company are a total joke. Oh, and they are liars, too. Amazing it's taking some people so long to figure it out.
