I signed up for that a couple weeks ago. So far I've only got one task which involved an airdrop of Zcoin, which was kind of interesting; it had me set up a wallet and join their Telegram group, as well as other things I might be forgetting.
I also signed up to be on their contact lists under various things I'm experienced in. Unfortunately, no contacts on that frunt so far. I'm betting that part of the system isn't very much used.
Just FYI, it's considered good practice to clearly disclose referral links.
