Any platforms with really good sign up bonuses?

Recently found KCEX, which is no kyc and will give you 200 in bonus money for following them on twitter, even when depositing zero dollars. I had five different twitter accounts(they need to be active for 90 days and have 20 followers) which I used for this on different KCEX accounts. I took the opposite sides of a few trades and basically made like $400 easy doing this. Are there any other platforms out there doing crazy promotions like this?
