just received another email, but the bonus link inside the email is just the same with the last bonus link I got in March 28
are you trying to spam?
I got it April's fool bonus, redeemed without any problem.
But a few weeks ago I received an email, and clicked the link, it also showed "redeemed". Now you have the same problem which I had before.
And 2 days I got the withdrawal of my second bonus(received on 28th of March). Now the bonus code doesn't have any rollover, you can just withdraw it.

Yeap it works for me now, but it still with rollover requirement.
