Looks like they can only guarantee to stay up till the end of the month. From their website:

There has been some major disruption with our technical team based in Ukraine and we are not currently able to offer bundles. That may change, we can guarantee users will be able to download their assets through the end of July 2022. We will keep you informed about the future of Groupees here and on social media. Thank you.

Groupees used to be a site with great game bundles but like all bundle sites their game offers have been less than stellar lately and they've mostly been doing music and comic bundles recently.
