Double bonus for Polymarket?

Can someone tell me if you're supposed to only be able to redeem Polymarket bonuses twice? For context, I made an account last week to claim the bonus but after blowing my account, I used a new code link and got the bonus again, basically getting $140 total. This what i used https://polymarket.us/IU20
