They are recycling all of their old sets. Took a bit to find but here is the statement from their website.

TOKYODOLL.tv will stop updating photo and video data after the last data update on October 21, 2023. This is due to the recent world situation and our company’s management.
In the future, TOKYODOLL.tv will return to the first update on 2015, so if you need to cancel your membership or change your payment period, please do so.
Thank you very much for your long term use since 2015.

Is a pity as their content has a unique feel to it.
