Definitely something fishy going on here. I referred a bunch of people and tried to maximize my rewards, but my account is showing less than 500 STAC which is currently worth around $5. I was expecting to get at least $100 or more. I'm not sure if I have screenshots of the previous balances, but I remember being shocked when they suddenly changed the numbers one day. Looks like they've done it again.

Smells like scam
